This makes the clang-format plugin self-contained. Instead of
requiring clang-format.exe to be available on the PATH, this
includes it in the plugin's installer (.vsix file) and runs it
from the install directory.

Re-enabled support for the Subjects for the weak attribute. This changes the diagnostic involved to be more accurate -- for C++ code, it will now report that weak applies to variables, functions or classes. Added additional test case for this.

This avoids allocation of temporary std::strings for file contents, instead
writing chunks directly to the output stream.

The old character-based B-tree iterator remains intact for the time being.

Found two identical files named 'DefaultOnly.h' in the libcxx test suite. Moved one to /support, removed the other, and iupdated all the includes. No functionality change

The __w64 attribute handler was more generically named, but only applied to __w64 specifically. Renamed and removed some unused code. No functional change intended.

MO_JumpTableIndex and MO_ExternalSymbol don't show up on inline asm.

Keeping parts of the old asm printer just to print inline asm to a string that
we then parse back looks like a hack.

Summary:
Added -fallback-style option. Changed clang-format to stop searching
for .clang-format when an invalid file is found.

The profile file parser needed some tests for its parsing actions.
This adds tests for each of the error messages emitted by the parser.

A number of tests fail to build on FreeBSD because the test build script
defaults to libstdc++ for clang.  On FreeBSD the libstdc++ is rather old
and libc++ should be used instead.

(These tests previously had an @expectedFailureFreeBSD decorator for
pr16696, the umbrella PR for the lack of threaded inferior support on
FreeBSD.  The work to add that support will be committed soon.)

When a block is unreachable, asking its dom tree descendants should
return the empty set. However, the computation of the descendants
was causing a segmentation fault because the dom tree node we get
from the basic block is initially NULL.

Fixed by adding a test for a valid dom tree node before we iterate.

The patch also adds some unit tests to the existing dom tree tests.

eliminateFrameIndex() has been reworked to handle both small & large frames
with either a FP or SP.
An additional Slot is required for Scavenging spills when not using FP for large frames.
Reworked the handling of Register Scavenging.

Whether we are using an FP or not, whether it is a large frame or not,
and whether we are using a large code model or not are now independent.

These are used by MachO only at the moment, and (much like the existing
MOVW/MOVT set) work around the fact that the labels used in the actual
instructions often contain PC-dependent components, which means that repeatedly
materialising the same global can't be CSEed.

With small modifications, it could be adapted to how ELF finds the address of
_GLOBAL_OFFSET_TABLE_, which would give similar benefits in PIC mode there.

When using large code model:
Global objects larger than 'CodeModelLargeSize' bytes are placed in sections named with a trailing ".large"
The folded global address of such objects are lowered into the const pool.

During inspection it was noted that LowerConstantPool() was using a default offset of zero.
A fix was made, but due to only offsets of zero being generated, testing only verifies the change is not detrimental.

Correct the flags emitted for explicitly specified sections.

We assume the size of the object queried by getSectionForConstant() is never greater than CodeModelLargeSize.
To handle greater than CodeModelLargeSize, changes to AsmPrinter would be required.

Large frame offsets are loaded from the ConstantPool.
Where possible, offsets are encoded using the smaller MKMSK instruction.
Large frame offsets can only be used when there is a frame-pointer.
