36e36ace77 Fix issues in shuffle decoding around VPERM* instructions. Fix shuffle decoding for VSHUFPS/D for 256-bit types. Add pattern matching for memory forms of VPERMILPS/VPERMILPD.

5d2f8c3155 [Win32] Catch exceptions (eg. segfault) on waiting for invoked clang from the driver. 
clang/lib/Driver/Driver.cpp: Don't pass through negative exit status, or parent would be confused.

llvm::sys::Program::Wait(): Suppose 0x8000XXXX and 0xC000XXXX as abnormal exit code and pass it as negative value.

Win32 Exception Handler: Exit with ExceptionCode on an unhandle exception.

ecb35ece5c SCEV fix. In general, Add/Mul expressions should not inherit NSW/NUW. 
This reverts r139450, fixes r139453, and adds much needed comments and a
unit test.

d7c2494b3c On MachO, the pointer to the personality function should always be in the 
non_lazy_symbol_pointers section (__IMPORT,__pointers). Ignore the 'hidden' part
since that will place it in the wrong section.

   change passes the bots.

cc966de237 Add a link from the LLVM release notes to the Clang release notes. 
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.

ed1c0c7f58 Revert r145273 and fix in SelectionDAG::InferPtrAlignment() instead. 
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.

ae7e2a4bbb Add an optional separate install prefix for internal components. rdar://10217046 
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.
