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.

remove dead nullptr checks
ClangASTContext::getASTContext() currently returns a ptr but we have an assert there since a
while that the ASTContext is not a nullptr. This causes that we still have a lot of code
that is doing nullptr checks on the result of getASTContext() which is all unreachable code.
This patch changes the return value to a reference to make it clear this can't be a nullptr
and deletes all the nullptr checks.

Their naming is misleading as they only return the
ClangASTContext-owned variables. For ClangASTContext instances constructed
for a given clang::ASTContext they silently generated duplicated instances
(e.g., a second IdentifierTable) that were essentially unusable.
This removes all these getters as they are anyway not very useful in comparison
to just calling the clang::ASTContext getters. The initialization
code has been moved to the CreateASTContext initialization method so that all
code for making our own clang::ASTContext is in one place.

The EXCLUDE_FROM_ALL variable is used by add_llvm_library, but lldb does
not use that function (it uses llvm_add_library :P). Instead, set the directory
property with the same name directly.
This should fix standalone builds against an llvm install tree.

This patch added some gtest code to the TestingSupport library. As this
is not a unit test, but a unit test library, gtest does not get added to
the include path automatically, but we have to do that ourselves. (It
was working for me without this because the compiler picked up the
system gtest instead.)

Summary:
Recently, yaml2obj has been turned into a library. This means we can use
it from our unit tests directly, instead of shelling out to an external
process. This patch does just that.

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' "{}" +

Summary:
This is the third patch to improve module loading in a series that started here (where I explain the motivation and solution): D62499
Add functions to read the r_debug location to know where the linked list of loaded libraries are so I can generate the `xfer:libraries-svr4` packet.
I'm also using this function to implement `GetSharedLibraryInfoAddress` that was "not implemented" for linux.
Most of this code was inspired by the current ds2 implementation here: https://github.com/facebook/ds2/blob/master/Sources/Target/POSIX/ELFProcess.cpp.

Checking this in for Antonio Afonso:
This diff changes the function LineEntry::GetSameLineContiguousAddressRange so that it also includes function calls that were inlined at the same line of code.
My motivation is to decrease the step over time of lines that heavly rely on inlined functions. I have multiple examples in the code base I work that makes a step over stop 20 or mote times internally. This can easly had up to step overs that take >500ms which I was able to lower to 25ms with this new strategy.
The reason the current code is not extending the address range beyond an inlined function is because when we resolve the symbol at the next address of the line entry we will get the entry line corresponding to where the original code for the inline function lives, making us barely extend the range. This then will end up on a step over having to stop multiple times everytime there's an inlined function.
To check if the range is an inlined function at that line I also get the block associated with the next address and check if there is a parent block with a call site at the line we're trying to extend.
To check this I created a new function in Block called GetContainingInlinedBlockWithCallSite that does exactly that. I also added a new function to Declaration for convinence of checking file/line named CompareFileAndLine.
To avoid potential issues when extending an address range I added an Extend function that extends the range by the AddressRange given as an argument. This function returns true to indicate sucess when the rage was agumented, false otherwise (e.g.: the ranges are not connected). The reason I do is to make sure that we're not just blindly extending complete_line_range by whatever GetByteSize() we got. If for some reason the ranges are not connected or overlap, or even 0, this could be an issue.
I also added a unit tests for this change and include the instructions on the test itself on how to generate the yaml file I use for testing.

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.

The whole point of this change was making it possible to resolve paths
without depending on the FileSystem, which is not what I did here. Not
sure what I was thinking...

In order to call real_path from the TildeExpressionResolver we need
access to the FileSystem. Since the resolver lives under utility we have
to pass in the FS.

Summary:
At present, several gtests in the lldb open source codebase are using
#include statements rooted at $(SOURCE_ROOT)/${LLDB_PROJECT_ROOT}.
This patch cleans up this directory/include structure for both CMake and
Xcode build systems.
