When Sema::RequireCompleteType() is given a class template
specialization type that then fails to instantiate, it returns
'true'. On subsequent invocations, it can return false. Make sure that
this difference doesn't change the result of
Sema::CompareReferenceRelationship, which is expected to remain stable
while we're checking an initialization sequence.

Required making a handful of changes to the table generator. Also adds
an unspecified inheritance attribute. This opens the path for us to
apply these attributes to C++ records implicitly.

Initialize CalleeWithThisReturn to 0 in the constructor.
Also revert r170815 since checking CalleeWithThisReturn is faster.

- Add head 'prfchwintrin.h' to define '_m_prefetchw' which is mapped to
LLVM/clang prefetch builtin
- Add option '-mprfchw' to enable PRFCHW feature and pre-define '__PRFCHW__'

For each macro directive (define, undefine, visibility) have a separate object that gets chained
to the macro directive history. This has several benefits:
-No need to mutate a MacroDirective when there is a undefine/visibility directive. Stuff like
PPMutationListener become unnecessary.
-No need to keep extra source locations for the undef/visibility locations for the define directive object
(which is the majority of the directives)
-Much easier to hide/unhide a section in the macro directive history.
-Easier to track the effects of the directives across different submodules.

Summary:
The only vector types a user can pass from MSVC code to clang code are
the ones from *mmintrin.h, so we only have to match the MSVC mangling
for these types. MSVC mangles the __m128 family of types as tag types,
which we match. For other vector types, we emit a unique tag type
mangling that won't match anything produced by MSVC.

CalleeWithThisReturn can be left initialized if HasThisReturn() is false.
This change reverses the order of checks in EmitFunctionEpilog such that
CalleeWithThisReturn is only examined when it has a meaningful value.
Found with MemorySanitizer.

LLVMBuild stuff didn't actually provide a single place for dependencies,
it just added a third place.

difference is that we no longer clean the token before emitting it. This fixes a bug where
clang hangs in the middle of crashing because the crash handler calls malloc from inside
a crash that happened inside of free.

If the ASM statement is dereferencing an incomplete pointer type, issue an error
instead of crashing.

This addresses an undefined value false positive from concreteOffsetBindingIsInvalidatedBySymbolicOffsetAssignment.

These aren't generated by default, but they are needed when either side of
the comparison is tainted.
Should fix our internal buildbot.
