Piotr Padlewski 610c966a4e Handle invariant.group.barrier in BasicAA
Summary:
llvm.invariant.group.barrier returns pointer that mustalias
pointer it takes. It can't be marked with `returned` attribute,
because it would be remove easily. The other reason is that
only Alias Analysis can know about this, because if any other
pass would know it, then the result would be replaced with it's
argument, which would be invalid.

We can think about returned pointer as something that mustalias, but
it doesn't have to be bitwise the same as the argument.

Zachary Turner b471d4f25a Teach lit to expand glob expressions.
This will enable removing hacks throughout the codebase
in clang and compiler-rt that feed multiple inputs to a
testing utility by globbing, all of which are either disabled
on Windows currently or using xargs / find hacks.

Jordan Rose 88eb534517 Teach llvm-bcanalyzer to use one stream's BLOCKINFO to read another stream.
This allows streams that only use BLOCKINFO for debugging purposes to omit
the block entirely. As long as another stream is available with the correct
BLOCKINFO, the first stream can still be analyzed and dumped.

As part of this commit, BitstreamReader gets a move constructor and move
assignment operator, as well as a takeBlockInfo method.

Matt Beaumont-Gay 8b30c13e12 (1) Add ".test" to test/Other/lit.local.cfg, so llvm-cov.test is actually run.
(2) Rename llvm-cov test inputs so the string "llvm-cov" doesn't get
substituted by lit within the input filenames on the RUN line.
(3) XFAIL llvm-cov.test because it asserts:
include/llvm/ADT/SmallVector.h:140: reference llvm::SmallVectorTemplateCommon<llvm::GCOVBlock *, void>::operator[](unsigned int) [T = llvm::GCOVBlock *]: Assertion `begin() + idx < end()' failed.
