Store in PCH the directory that the PCH was originally created in.
If a header file is not found at the path that we expect it to be and the PCH file
was moved from its original location, try to resolve the file by assuming that
header+PCH were moved together and the header is in the same place relative to the PCH.

Add a bunch of utilities and an enum (ARM_ShifterType) for shift and rotate operations pertaining to:

o A2.2.1 Pseudocode details of shift and rotate operations
o A8.4.3 Pseudocode details of instruction-specified shifts and rotates

  - Have CGM precompute a number of commonly-used types
  - Have CGF copy that during initialization instead of recomputing them
  - Use TBAA info when initializing a parameter variable
  - Refactor the scalar ++/-- code

-Update tablegen files for checkers, use the tablegen class name for the checker class name.
-Update ClangSACheckersProvider to not look into hidden checker packages.

StackAddrLeakChecker
ObjCAtSyncChecker

The rest have/create implicit dependencies between checkers and need to be handled differently.

Fix 9216 - Endless loop in InstCombine pass.
The pattern "A&(A^B) -> A & ~B" recreated itself because ~B is
actually a xor -1.

the parser will complete the declarator with a valid decl and thus trigger
delayed diagnostics for it.  It certainly looks like we were intentionally
returning null here, but I couldn't find any good reason for it, and there
wasn't a comment, so farewell to all that.

a zero constant for a complete class.  rdar://problem/8424975

To make this happen, track the field indexes for virtual bases
in the complete object.  I'm curious whether we might be better
off making CGRecordLayoutBuilder *much* more reliant on
ASTRecordLayout;  we're currently duplicating an awful lot of the ABI
layout logic.

ArchDefaultUnwindPlan plug-in interfaces are now cached per architecture 
instead of being leaked for every frame.

Split the ArchDefaultUnwindPlan_x86 into ArchDefaultUnwindPlan_x86_64 and
ArchDefaultUnwindPlan_i386 interfaces.

There were sporadic crashes that were due to something leaking or being 
destroyed when doing stack crawls. This patch should clear up these issues.

Simplify the spill weight calculation a bit by bypassing
getApproximateInstructionCount() and using LiveInterval::getSize() directly.
This changes the computed spill weights, but only by a constant factor in each
function. It should not affect how spill weights compare against each other, and
so it shouldn't affect code generation.

Do not hoist @llvm.dbg.value. Here, @llvm.dbg.value is "referring" a value that is modified inside loop.
