No semantic analysis yet.

This is a pain to disambiguate correctly, because the parsing rules for the
declaration form of a condition and of an init-statement are quite different --
for a token sequence that looks like a declaration, we frequently need to
disambiguate all the way to the ')' or ';'.

We could do better here in some cases by stopping disambiguation once we've
decided whether we've got an expression or not (rather than keeping going until
we know whether it's an init-statement declaration or a condition declaration),
by unifying our parsing code for the two types of declaration and moving the
syntactic checks into Sema; if this has a measurable impact on parsing
performance, I'll look into that.

[ClangConfig] Copy ClangConfig.cmake to ${CMAKE_BINARY_DIR}/${CLANG_INSTALL_PACKAGE_DIR} instead of to ${CLANG_BINARY_DIR}/${CLANG_INSTALL_PACKAGE_DIR}.

This is an obvious bug since ClangConfig.cmake looks for ClangTargets.cmake in
${CMAKE_CURRENT_LIST_DIR}. But ClangTargets.cmake is in
${CMAKE_BINARY_DIR}/${CLANG_INSTALL_PACKAGE_DIR}, so it will always fail with an
in tree build.

In the case where clang is built out of tree, this is still correct since
CMAKE_BINARY_DIR and CLANG_BINARY_DIR will be the same.

This is a fix for PR27842.

An IR-level implementation of stack coloring tailored to work with
SafeStack. It is a bit weaker than the MI implementation in that it
does not the "lifetime start at first access" logic. This can be
improved in the future.

This patch also replaces the naive implementation of stack frame
layout with a greedy algorithm that can split existing stack slots
and even fit small objects inside the alignment padding of other
objects.

Summary: Take advantage of FCmpInst::Predicate's bit pattern and handle (fcmp *, x, y) | (fcmp *, x, y) and (fcmp *, x, y) & (fcmp *, x, y) more consistently. Also fold more FCmpInst::FCMP_FALSE and FCmpInst::FCMP_TRUE to constants.

Currently InstCombine wrongly folds (fcmp ogt, x, y) | (fcmp ord, x, y) to (fcmp ogt, x, y); this patch also fixes that.

Summary:
On windows, the debug information was not present in the unittest executables,
which make them hard to debug.

The Sanitizer Unittests are compiled with a local clang build.
The link pass is also done by calling clang.

This pass is adding the appropriate flags to bring the right debug information
to these executables.

This rewrite of the omp_sections_nowait.c test file causes it to hang if the
nowait is not respected. If the nowait isn't respected, the lone thread which
can escape the first sections construct will just sleep at a barrier which
shouldn't exist. All reliance on timers is taken out. For good measure, the test
makes sure that all eight sections are executed as well. The test should take no
longer than a few seconds on any modern machine.

This fixes pr28072.

The point, as Duncan pointed out, is that the file is already
partially linked by just reading it.

Long term I think the solution is to make metadata owned by the module
and then the linker will lazily read it and be in charge of all the
linking. Running a verifier in each input will defeat the lazy
loading, but will be legal.

Right now we are at the unfortunate position that to support odr
merging we cannot verify the inputs, which mildly annoying (see test
update).

Reverts r273305 and re-instates r273296.

We needed to fix a bug in Sema::MarkVTableUsed to ensure that operator
delete lookup occurs when the vtable is referenced. We already had a
special case to look up operator delete when dllimport was used, but I
think should really mark virtual destructors referenced any time the
vtable is used.

When lowering two blended PACKUS, we used to disregard the types
of the PACKUS inputs, indiscriminately generating a v16i8 PACKUS.

This leads to non-selectable things like:
    (v16i8 (PACKUS (v4i32 v0), (v4i32 v1)))

Instead, check that the PACKUSes have the same type, and use that
as the final result type.

This gets rid of the memory fence in the hot path (dereferencing the
ManagedStatic), trading for an extra mutex lock in the cold path (when
the ManagedStatic was uninitialized). Since this only happens on the
first accesses it shouldn't matter much. On strict architectures like
x86 this removes any atomic instructions from the hot path.

Also remove the tsan annotations, tsan knows how standard atomics work
so they should be unnecessary now.
