We recognize a splat from element 0 in (VectorUtils) llvm::getSplatValue()
and also in ShuffleVectorInst::isZeroEltSplatMask(), so this converts
to that form for better matching.

The backend generically turns these patterns into build_vector,
so there should be no codegen difference.

The IRBuilder has calls to create floating point instructions like fadd.
It does not have calls to create constrained versions of them. This patch
adds support for constrained creation of fadd, fsub, fmul, fdiv, and frem.

Summary:
__kmpc_push_tripcount function is not thread safe and may lead to data
race when the target regions are executed in parallel threads. The patch
makes loopTripCnt counter thread aware and stores the tripcount value
per thread in the map. Access to map is guarded by mutex to prevent
data race in the map itself.
Test is for NVPTX target because it does not work correctly on the
host. Seems to me, there is a problem in libomp with target regions in
the parallel threads.

Summary:
Otherwise, when libcxxabi is not an enabled project in the monorepo, we
get a link error because we try to link against non-existent cxxabi_shared.

More generally, we shouldn't change the behavior of the build based on
implicit things like whether a file happens to be at a specific path or
not.

This is a re-application of r365222 that had been reverted in r365233
because it broke the build bots. However, the build bots now specify
explicitly what ABI library they want to use (libc++abi), so this
commit should now be OK to merge.

Summary:
Currently SHA1 is about 10% of our CPU, this patch reduces it to ~1%.

xxhash is a well-defined (stable) non-cryptographic hash optimized for
fast checksums (like crc32).
Collisions shouldn't be a problem, despite the reduced length:
 - for actual file content (used to invalidate bg index shards), there
   are only two versions that can collide (new shard and old shard).
 - for file paths in bg index shard filenames, we would need 2^32 files
   with the same filename to expect a collision. Imperfect hashing may
   reduce this a bit but it's well beyond what's plausible.

This will invalidate shards on disk (as usual; I bumped the version),
but this time the filenames are changing so the old files will stick
around :-( So this is more expensive than the usual bump, but would be
good to land before the v9 branch when everyone will start using bg index.
