a3437f732e Allow getting the address of the value in a PointerUnion or PointerIntPair if one is 
confident enough that he knows what he is doing.

9f386640da Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't 
need to be pulled out of the pass manager when the user specifies 
-fno-builtin.  It can intelligently determine which libcalls to
optimize based on what is enabled in TargetLibraryInfo.  This 
allows -fno-builtin-foo to work someday.

a2d2de33c5 Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for fixed-length instruction encodings. 
A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks
provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen
like the existing disassembly emitters do.

The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove
some of the hacks the old one introduced to tblgen.

63dfb2c797 introduce a new TargetLibraryInfo pass, which transformations can use to 
query about available library functions.  For now this just has 
memset_pattern16, which exists on darwin, but it can be extended for a 
bunch of other things in the future.

00228d0c2c Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way.

70f48f08c1 Move more fragments of spill weight calculation into CalcSpillWeights.h 
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.

cf712db15a add a new ArrayRef class. This is intended to replace the idiom we 
use in many places where we pass a pointer and size to abstract APIs
that can take C arrays, std::vector, SmallVector, etc.  It is to arrays
what StringRef is to strings.

c9c0de6faf Revisit my fix for PR9028: the issue is that DAGCombine was 
generating i8 shift amounts for things like i1024 types.  Add
an assert in getNode to prevent this from occuring in the future,
fix the buggy transformation, revert my previous patch, and
document this gotcha in ISDOpcodes.h
