Terminate in the unit tests
Summary:
Many of our tests need to initialize certain subsystems/plugins of LLDB such as
`FileSystem` or `HostInfo` by calling their static `Initialize` functions before the
test starts and then calling `::Terminate` after the test is done (in reverse order).
This adds a lot of error-prone boilerplate code to our testing code.
This patch adds a RAII called SubsystemRAII that ensures that we always call
::Initialize and then call ::Terminate after the test is done (and that the Terminate
calls are always in the reverse order of the ::Initialize calls). It also gets rid of
all of the boilerplate that we had for these calls.
Per-fixture initialization is still not very nice with this approach as it would
require some kind of static unique_ptr that gets manually assigned/reseted
from the gtest SetUpTestCase/TearDownTestCase functions. Because of that
I changed all per-fixture setup to now do per-test setup which can be done
by just having the SubsystemRAII as a member of the test fixture. This change doesn't
influence our normal test runtime as LIT anyway runs each test case separately
(and the Initialize/Terminate calls are anyway not very expensive). It will however
make running all tests in a single executable slightly slower.

Summary:
This patch adds code which will substitute references to the full object
constructors/destructors with their base object versions.
Like all substitutions in this category, this operation is not really
sound, but doing this in a more precise way allows us to get rid of a
much larger hack -- matching function according to their demangled
names, which effectively does the same thing, but also much more.
This is a (very late) follow-up to D54074.
Background: clang has an optimization which can eliminate full object
structors completely, if they are found to be equivalent to their base
object versions. It does this because it assumes they can be regenerated
on demand in the compile unit that needs them (e.g., because they are
declared inline). However, this doesn't work for the debugging scenario,
where we don't have the structor bodies available -- we pretend all
constructors are defined out-of-line as far as clang is concerned. This
causes clang to emit references to the (nonexisting) full object
structors during expression evaluation.
Fun fact: This is not a problem on darwin, because the relevant
optimization is disabled to work around a linker bug.

Summary:
Clang's raw Lexer doesn't produce any tokens for trailing backslashes in a line. This doesn't work with
LLDB's Clang highlighter which builds the source code to display from the list of tokens the Lexer returns.
This causes that lines with trailing backslashes are lacking the backslash and the following newline when
rendering source code in LLDB.
This patch removes the trailing newline from the current line we are highlighting. This way Clang doesn't
drop the backslash token and we just restore the newline after tokenising.

There is likely also an underlying bug in all code that calls
CPlusPlusNameParser with nullptrs, but this patch can also stand for
itself.

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

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.

Summary:
Now that llvm demangler supports more generic customization, we can
implement type substitution directly on top of this API. This will allow
us to remove the specialized hooks which were added to the demangler to
support this use case.

This patch introduces the simple MSVCUndecoratedNameParser. It is needed for
parsing names of PDB symbols corresponding to template instantiations. For
example, for the name `operator<<A>'::`2'::B::operator> we can't just split the
name with :: (as it is implemented for now) to retrieve its scopes. This parser
processes such names in a more correct way.

In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.
This patch removes the OCaml debugger plugin.
The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.

Summary:
The syntax highlighting feature so far is mutually exclusive with the lldb feature
that marks the current column in the line by underlining it via an ANSI color code.
Meaning that if you enable one, the other is automatically disabled by LLDB.
This was caused by the fact that both features inserted color codes into the the
source code and were likely to interfere with each other (which would result
in a broken source code printout to the user).
This patch moves the cursor code into the highlighting framework, which provides
the same feature to the user in normal non-C source code. For any source code
that is highlighted by Clang, we now also have cursor marking for the whole token
that is under the current source location. E.g., before we underlined only the '!' in the
expression '1 != 2', but now the whole token '!=' is underlined. The same for function
calls and so on. Below you can see two examples where we before only underlined
the first character of the token, but now underline the whole token.
{F7075400}
{F7075414}
It also simplifies the DisplaySourceLines method in the SourceManager as most of
the code in there was essentially just for getting this column marker to work as
a FormatEntity.

Summary:
Removing FastDemangle will greatly reduce maintenance efforts. This patch replaces the last point of use in LLDB. Semantics should be kept intact.
Once this is agreed upon, we can:
* Remove the FastDemangle sources
* Add more features e.g. substitutions in template parameters, considering all variations, etc.

Summary:
This patch adds syntax highlighting support to LLDB. When enabled (and lldb is allowed
to use colors), printed source code is annotated with the ANSI color escape sequences.
So far we have only one highlighter which is based on Clang and is responsible for all
languages that are supported by Clang. It essentially just runs the raw lexer over the input
and then surrounds the specific tokens with the configured escape sequences.

Current implementation of CPlusPlusLanguage::MethodName::Parse() doesn't
get anywhere close to covering full extent of possible function declarations.
It causes incorrect behavior in avoid-stepping and sometimes messes
printing of thread backtrace.
This change implements more methodical parsing logic based on clang
lexer and simple recursive parser.
Examples:
void std::vector<Class, std::allocator<Class>>::_M_emplace_back_aux<Class const&>(Class const&)
void (*&std::_Any_data::_M_access<void (*)()>())()
Previous version of this change (D31451) was rolled back due to an issue
with Objective-C selectors being incorrectly recognized as a C++ identifier.

This caused a failure in the test case:
functionalities/breakpoint/objc/TestObjCBreakpoints.py
When we are parsing up names we stick interesting parts of the names
in various buckets, one of which is the ObjC selector bucket. The new
C++ name parser must be interfering with this process somehow.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Summary:
CPlusPlusLanguage::MethodName was not correctly parsing templated functions whose demangled name
included the return type -- the space before the function name was included in the "context" and
the context itself was not terminated correctly due to a misuse of the substr function (second
argument is length, not the end position). Fix that and add a regression test.
