StmtDumper.cpp is called ASTDumper.cpp these days, and usually works well
for new AST nodes without changes.  There's now DataRecursiveASTVisitor
in addition to RecursiveASTVisitor, and serialization wasn't mentioned.

Codegen is still missing (and I won't work on that), but __leave is now
as implemented as __try and friends.

Give scope a SEHTryScope bit, set that in ParseSEHTry(), and let Sema
walk the scope chain to find the SEHTry parent on __leave statements.
(They are rare enough that it seems better to do the walk instead of
giving Scope a SEHTryParent pointer -- this is similar to AtCatchScope.)

The MicrosoftExtensions.c test file should not rely on -x objective-c++. Removed that from the RUN line, fixed obvious C++isms in the code, and moved some C++ tests into MicrosoftExtensions.cpp instead. As a drive-by, changed the line endings for MicrosoftExtensions.c to be LF instead of CRLF.

Summary:
This gives us back the test coverage we lost when I made
MicrosoftExtensions.c x86-only.

Although these aren't strictly related to LLVM's core threading, it's
reasonable to avoid pthread usage in clang when building with
LLVM_ENABLE_THREADS disabled.

This type is only refcounted in a couple of places so making ownership explicit
improves clarity.

This makes it clear that TargetInfo doesn't capture the LangOptions object,
rather uses it to apply adjustments.

This adds support for simple MSVC compatibility mode intrinsics.  These
intrinsics are simple in that they are either directly passed through to the
annotated MSBuiltin intrinsic or they mirror existing GCC builtins.

This completes the infrastructure for the new MSBuiltin aliases in the
instruction definitions.  These behave similar to the GCCBuiltin in that they
can be implicitly constructed without special handling unless needed.

With this change it is possible to annotate an LLVM intrinsic in the backend
instruction definitions and indicate it as a builtin in the Builtin*.def files
in clang via LANGBUILTIN.  That will automatically pass through the instruction
much as a GCCBuiltin.

Note that there is no need for the special handling for ensuring that the
compatibility flag is enabled since the filtering on the LANGBUILTIN will
automatically prevent the intrinsic from bleeding into non-MS compatible
compiler invocations.

These are forms that have either slipped in without being requested for
compatibility or that GCC doesn't support in the first place.
