Summary:
This patch fixes a bug where when target triple created from elf information
is arm-*-linux-eabihf and platform triple is armv8l-*-linux-gnueabihf. Merging
both triple results in armv8l--unknown-unknown.
This happens because we order a triple update while calling CoreUpdated and
CoreUpdated creates a new triple with no vendor or environment information.
Making sure we do not update triple and just update to more specific core
fixes the issue.

Windows on ARM always uses thumb mode, and doesn't have most of the

This patch adds core definitions in lldb ArchSpecs for armv8l and armv7l cores.
This was needed because on Linux running on 32-bit Arm v8 we are returned
armv8l in case we are running 32-bit sysroot on 64bit kernel. In case of 32-bit
kernel and 32-bit sysroot running on arm v8 hardware we are returned armv7l.
This is quite common when we run 32 bit arm using docker container.

gcc-9 started warning when a class defined a copy constructor without a
copy assignment operator (or vice-versa).
This fixes those warnings by deleting the other special member too

Add a test case for the change from SVN r372657, and for the
preexisting ARM identification.
Add a missing ArchDefinitionEntry for PECOFF/arm64, and tweak
the ArmNt case to set the architecture to armv7 (ArmNt never ran
on anything lower than that). (This avoids a case where
ArchSpec::MergeFrom would override the arch from arm to armv7 and
ArchSpec::CoreUpdated would reset the OS to unknown at the same time.)

remove any undocumented/redundant return values
Summary:
We still have some leftovers of the old completion API in the internals of
LLDB that haven't been replaced by the new CompletionRequest. These leftovers
are:
* The return values (int/size_t) in all completion functions.
* Our result array that starts indexing at 1.
* `WordComplete` mode.
I didn't replace them back then because it's tricky to figure out what exactly they
are used for and the completion code is relatively untested. I finally got around
to writing more tests for the API and understanding the semantics, so I think it's
a good time to get rid of them.
A few words why those things should be removed/replaced:
* The return values are really cryptic, partly redundant and rarely documented.
They are also completely ignored by Xcode, so whatever information they contain will end up
breaking Xcode's completion mechanism. They are also partly impossible to even implement
as we assign negative values special meaning and our completion API sometimes returns size_t.
Completion functions are supposed to return -2 to rewrite the current line. We seem to use this
in some untested code path to expand the history repeat character to the full command, but
I haven't figured out why that doesn't work at the moment.
Completion functions return -1 to 'insert the completion character', but that isn't implemented
(even though we seem to activate this feature in LLDB sometimes).
All positive values have to match the number of results. This is obviously just redundant information
as the user can just look at the result list to get that information (which is what Xcode does).
* The result array that starts indexing at 1 is obviously unexpected. The first element of the array is
reserved for the common prefix of all completions (e.g. "foobar" and "footar" -> "foo"). The idea is
that we calculate this to make the life of the API caller easier, but obviously forcing people to have
1-based indices is not helpful (or even worse, forces them to manually copy the results to make it
0-based like Xcode has to do).
* The `WordComplete` mode indicates that LLDB should enter a space behind the completion. The
idea is that we let the top-level API know that we just provided a full completion. Interestingly we
`WordComplete` is just a single bool that somehow represents all N completions. And we always
provide full completions in LLDB, so in theory it should always be true.
The only use it currently serves is providing redundant information about whether we have a single
definitive completion or not (which we already know from the number of results we get).
This patch essentially removes `WordComplete` mode and makes the result array indexed from 0.
It also removes all return values from all internal completion functions. The only non-redundant information
they contain is about rewriting the current line (which is broken), so that functionality was moved
to the CompletionRequest API. So you can now do `addCompletion("blub", "description", CompletionMode::RewriteLine)`
to do the same.
For the SB API we emulate the old behaviour by making the array indexed from 1 again with the common
prefix at index 0. I didn't keep the special negative return codes as we either never sent them before (e.g. -2) or we
didn't even implement them in the Editline handler (e.g. -1).
I tried to keep this patch minimal and I'm aware we can probably now even further simplify a bunch of related code,
but I would prefer doing this in follow-up NFC commits

This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.
find . -type f -name '*.cpp' -exec \
sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +

Previous ArchSpec tests didn't catch this bug since we never tested just the OS being out of date. Fixed the bug and covered this with a test that would catch this.
This was found when trying to load a core file where the core file was an ELF file with just the e_machine for architeture and where the ELF header had no OS set in the OSABI field of the e_ident. It wasn't merging the architecture with the target architecture correctly.

My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.
ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

Summary:
This behavior was originally added in rL252264 (git commit 76a7f365da)
in order to be extra careful with handling platforms like watchos and tvos.
However, as far as triples go, those two (and others) are treated as OSes and
not environments, so that should not really apply here.
Additionally, this behavior is incorrect and can lead to incorrect ArchSpecs.
Because android is specified as an environment and not an OS, not propogating
the environment can lead to modules and targets being misidentified.

Summary:
These functions should always return the opposite of the
`Triple{Environment,OS,Vendor}WasSpecified` functions. Unspecified unknown is
the same as unspecified, which is why one set of functions should give us what
we want. It's possible to have specified unknown, which is why we can't just
rely on checking the enum values of vendor/os/environment. We must also ensure
that the names of these are empty and not "unknown".

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This fixes a bug PlatformDarwin::SDKSupportsModule introduced by
https://reviews.llvm.org/D47889. VersionTuple::tryParse() can deal
with an optional third (micro) component, but the parse will fail when
there are extra characters after the version number (e.g.: trying to
parse the substring "12.0.sdk" out of "iPhoneSimulator12.0.sdk" fails
after that patch). Fixed here by stripping the ".sdk" suffix first.

Summary:
We currently allow any completion handler to read and manipulate the list of matches we
calculated so far. This leads to a few problems:
Firstly, a completion handler's logic can now depend on previously calculated results
by another handlers. No completion handler should have such an implicit dependency,
but the current API makes it likely that this could happen (or already happens). Especially
the fact that some completion handler deleted all previously calculated results can mess
things up right now.
Secondly, all completion handlers have knowledge about our internal data structures with
this API. This makes refactoring this internal data structure much harder than it should be.
Especially planned changes like the support of descriptions for completions are currently
giant patches because we have to refactor every single completion handler.
This patch narrows the contract the CompletionRequest has with the different handlers to:
1. A handler can suggest a completion.
2. A handler can ask how many suggestions we already have.
Point 2 obviously means we still have a dependency left between the different handlers, but
getting rid of this is too large to just append it to this patch.
Otherwise this patch just completely hides the internal StringList to the different handlers.
The CompletionRequest API now also ensures that the list of completions is unique and we
don't suggest the same value multiple times to the user. This property has been so far only
been ensured by the `Option` handler, but is now applied globally. This is part of this patch
as the OptionHandler is no longer able to implement this functionality itself.

Summary:
As suggested in D48796, this patch replaces even more internal calls that were using the old
completion API style with a single CompletionRequest. In some cases we also pass an option
vector/index, but as we don't always have this information, it currently is not part of the
CompletionRequest class.
The constructor of the CompletionRequest is now also more sensible. You only pass the
user input, cursor position and your list of matches to the request and the rest will be
inferred (using the same code we used before to calculate this). You also have to pass these
match window parameters to it, even though they are unused right now.
The patch shouldn't change any behavior.

Summary:
The ObjectFile class was used to determine the architecture of a running
process by inspecting it's main executable. There were two issues with
this:
- it's in the wrong layer
- the call can be very expensive (it can end up computing the crc of the
whole file).
Since the process is running on the host, ideally we would be able to
just query the data straight from the OS like darwin does, but there
doesn't seem to be a reasonable way to do that. So, this fixes the
layering issue by using the llvm object library to inspect the file.
Since we know the process is already running on the host, we just need
to peek at a few bytes of the elf header to determine whether it's 32-
or 64-bit (which should make this faster as well).
Pretty much the same logic was implemented in
NativeProcessProtocol::ResolveProcessArchitecture, so I delete this
logic and replace calls with GetProcessInfo.

The rationale here is that ArchSpec is used throughout the codebase,
including in places which should not depend on the rest of the code in
the Core module.
This commit touches many files, but most of it is just renaming of
#include lines. In a couple of cases, I removed the #include ArchSpec
line altogether, as the file was not using it. In one or two places,
this necessitated adding other #includes like lldb-private-defines.h.
