Major steps include:
1). introduces a not-addr-taken bit-field in GlobalVariable
2). GlobalOpt pass sets "not-address-taken" if it proves a global varirable
dosen't have its address taken.
3). AA use this info for disambiguation.

The second parameter of the SLD intrinsic is the number of columns (GPR) to
slide left the source array.

multiply-add long, signed saturating doubling multiply-subtract long, and
the signed saturating doubling multiply long instructions.

These were present in a previous version of the MSA spec but are not
present in the published version. There is no hardware that uses these
instructions.

Sadly this loses the checking from AssertingVH, but apparently storing the
end() of a BasicBlock into an AssertingVH has bad consequences as it's not
really an instruction.

Bitcasting everything to i8* won't work. Autoupgrade the old
intrinsic declarations to use the new mangling.

This is useful for some ARM intrinsics such as VCVTN which does a <4 x float> <-> <4 x half> conversion.

Inspired by the object from the SLPVectorizer. This found a minor bug in the
debug loc restoration in the vectorizer where the location of a following
instruction was attached instead of the location from the original instruction.

further lowered into a sequence of insert.w's on MIPS32.

The underlying type of all plain enums in MSVC is 'int', even if the
enumerator contains large 32-bit unsigned values or values greater than
UINT_MAX. The only way to get a large or unsigned enum type is to
request it explicitly with the C++11 strong enum types feature.
However, since LLVM isn't C++11 yet, I had to add a conditional
LLVM_ENUM_INT_TYPE to Compiler.h to control its usage.
The motivating true positive for this change is compiling PointerIntPair
with MSVC for win64. The PointerIntMask value is supposed to be pointer
sized value of all ones with some low zeros. Instead, it's truncated to
32-bits! We are only saved later because it is sign extended back in
the AND with int64_t, and we happen to want all ones.
This silences lots of -Wmicrosoft warnings during a clang self-host
targeting Windows.

Changes to MIPS SelectionDAG:
* Added nodes VEXTRACT_[SZ]EXT_ELT to represent extract and extend in a single
operation and implemented the DAG combines necessary to fold sign/zero
extends into the extract.

Add llvm.x86.* intrinsics for all of the Intel SHA Extensions instructions, as
well as tests. Also remove mayLoad and hasSideEffects, which can be inferred
from the instruction patterns.

If there are no legal integers, assume 1 byte.
This makes more sense than using the pointer size as
a guess for the maximum GPR width.
It is conceivable to want to use some 64-bit pointers
on a target where 64-bit integers aren't legal.

The work on this project was left in an unfinished and inconsistent state.
Hopefully someone will eventually get a chance to implement this feature, but
in the meantime, it is better to put things back the way the were. I have
left support in the bitcode reader to handle the case-range bitcode format,
so that we do not lose bitcode compatibility with the llvm 3.3 release.

instead of having its own implementation.
The implementation of isTBAAVtableAccess is in TypeBasedAliasAnalysis.cpp
since it is related to the format of TBAA metadata.
The path for struct-path tbaa will be exercised by
test/Instrumentation/ThreadSanitizer/read_from_global.ll, vptr_read.ll, and
vptr_update.ll when struct-path tbaa is on by default.
