- I verified locally that the current dependency lists are identical.
 - This makes add_llvm_library_dependencies() a no-op. I'll remove it once this
   change passes the bots.

Zap some completely ridiculous code.  There's probably a miscompile here, but I don't really want to try to write a testcase involving an invoke returning a pointer to a varargs function...

Replaces r145318 with a more targetted fix for the relocation handling.

SCEV can't optimize undef in all cases, which is a separate issue from this test case.

I suspect we could profitably remove/move some of the bullet points
under Clang here to the Clang notes in order to keep things clean on
both sides. Unless I hear objections I'll start doing that once folks
have read over the Clang notes a bit.

 - This fixes some layering violations and matches how we handle the llvm-c lib,
   for example.

to have control over what targets are available.

Make SelectionDAG::InferPtrAlignment use llvm::ComputeMaskedBits instead of duplicating the logic for globals.  Make llvm::ComputeMaskedBits handle GlobalVariables slightly more aggressively, to match what InferPtrAlignment knew how to do.

Conservatively returns zero when the GV does not specify an alignment nor is it
initialized. Previously it returns ABI alignment for type of the GV. However, if
the type is a "packed" type, then the under-specified alignments is attached to
the load / store instructions. In that case, the alignment of the type cannot be
trusted.

if !UseImm, in which case they have been initialized.

Add X86 instruction selection for VPERM2I128 when AVX2 is enabled. Merge VPERMILPS/VPERMILPD detection since they are pretty similar.

Some files installed by clang are not relevant for general users and we'd like
to be able to install them to a different location.  This adds a new
--with-internal-prefix configure option and a corresponding PROJ_internal_prefix
makefile variable, which defaults to the standard prefix.  A tool makefile
can specify that it should be installed to this internal prefix by defining
INTERNAL_TOOL.

lit/TestRunner.py: [Win32] Introduce WinWaitReleased(f), to wait for file handles to be released by children.

When wait() has finished, opened handles (especially writing stdout to file) might not be released immediately.
To wait for released, poll to attempt renaming.
