pointers, but accumulate the offset into an APInt in the process of
stripping it.

This is a pretty handy thing to have, such as when trying to determine
if two pointers are at some constant relative offset. I'll be committing
a patch shortly to use it for exactly that purpose.

PageSize, aka AllocationGranularity, is 65536 on Win32 (and Cygwin).

The AllocationGranularity can be 65536 on Win32, even on Cygwin.

Value. These methods probably don't belong here, and I'm discussing
moving the lot of them to a better home, but for now I'm about to extend
their functionality and wanted to tidy them up first.

Back in the mists of time (2008), it seems TableGen couldn't handle the
patterns necessary to match ARM's CMOV node that we convert select operations
to, so we wrote a lot of fairly hairy C++ to do it for us.

TableGen can deal with it now: there were a few minor differences to CodeGen
(see tests), but nothing obviously worse that I could see, so we should
probably address anything that *does* come up in a localised manner.

The code for 'Q' and 'R' operand modifiers needs to look through tied
operands to discover the register class.

[stackprotector] When finding the split point to splice off the end of a parentmbb into a successmbb, include any DBG_VALUE MI.

Indirect tail-calls shouldn't use R9 for the branch destination, as
it's not reliably a call-clobbered register.

When truncated vector stores were being custom lowered in
VectorLegalizer::LegalizeOp(), the old (illegal) and new (legal) node pair
was not being added to LegalizedNodes list.  Instead of the legalized
result being passed to VectorLegalizer::TranslateLegalizeResult(),
the result was being passed back into VectorLegalizer::LegalizeOp(),
which ended up adding a (new, new) pair to the list instead.

This was causing an assertion failure when a custom lowered truncated
vector store was the last instruction a basic block and the VectorLegalizer
was unable to find it in the LegalizedNodes list when updating the
DAG root.

This will make it easier to turn on struct-path aware TBAA since the metadata

Replace "(255 & value)" with "(0xFF & value)" to improve clarity.

The small utility function that pattern matches Base + Index +
Offset patterns for loads and stores fails to recognize the base
pointer for loads/stores from/into an array at offset 0 inside a
loop. As a result DAGCombiner::MergeConsecutiveStores was not able
to merge all stores.

This commit fixes the issue by adding an additional pattern match
and also a test case.

Summary:
This support will be utilized in things like clang to help check printf
format specifiers that are only valid when using the VSCRT.

[CMake] Automatically pick up subdirectories in llvm/tools as 'external projects' if they contain a 'CMakeLists.txt' file.

Allow CMake to pick up external projects in llvm/tools without the need to modify the "llvm/tools/CMakeLists.txt" file.
This makes it easier to work with projects that live in other repositories, without needing to specify each one in "llvm/tools/CMakeLists.txt".
