FreeBSD includes the elftoolchain project's demangler in the base system.
It does not handle some unusual mangled names, so use the inlined
libcxxabi one.

Do not use struct stat64 and struct statfs64 when building for iOS, where __DARWIN_ONLY_64_BIT_INO_T is set to 1.

This reverts commit r193479.

The atoms are already added to the file, so re-adding them caused the YAML
writer to write the same atoms twice. That made the YAML reader to fail with
"duplicate atom name" error.

This is not the only error we've got for RoundTripYAMLPass for PECOFF, so we
cannot enable the test yet. More fixes will come.

Fixes from code review by Jim Ingham that reinstate preferring an external vs non-external symbol when finding function addresses.

[ASan] Make asan_symbolize.py fall back to ASAN_SYMBOLIZER_PATH (which is used when ASAN_OPTIONS=symbolize=1) if LLVM_SYMBOLIZER_PATH is empty.

- can't think of a way to test this without generic lambda captures, but will include a test once that patch is made commit-ready.

patch was ok'd by Doug.

The same logic is present in ASan and TSan.

Some function definitions were using _CLC_DECL, which meant that they
weren't being marked as always_inline.

This will prevent LLVM optimization passes from creating illegal uses
of the barrier() intrinsic (e.g. calling barrier() from a conditional
that is not executed by all threads).

The isLValueReferenceType function checks to see if the QualType's
canonical type is an LValue reference, and not if the QualType
itself is an LValue reference.  This caused a segfault when trying
to cast the QualType's Type to a LValueReference.  This is now
fixed by casting the result of getCanonicalType().

In addition, a test was added to isConsumableType to prevent
segfaults when a type being tested by the analysis is a reference
to a pointer or a pointer to a reference.

As on other hosts, the CPU identification instruction is priveleged,
so we need to look through /proc/cpuinfo.  I copied the PowerPC way of
handling "generic".

Several tests were implicitly assuming z10 and so failed on z196.

Enables the clang driver to begin targeting specific CPUs. Introduced a
"generic" CPU which will ensure that the optional FP feature is enabled
by default when it gets to LLVM, without needing any extra arguments.
Cortex-A53 and A-57 are also introduced with tests, although backend
handling of them does not yet exist.

This adds a new subtarget feature called FPARMv8 (implied by NEON), and
predicates the support of the FP instructions and registers on this feature.
