bc4588c439 Re-commit 117518 and 117519 now that ARM MC test failures are out of the way.

fdc80a0316 Revert 117518 and 117519 for now. They changed scheduling and cause MC tests to fail. Ugh.

5c358e02ea - Assign load / store with shifter op address modes the right itinerary classes.
- For now, loads of [r, r] addressing mode is the same as the
  [r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
  identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
  is "free".

44d2802e1d Shifter ops are not always free. Do not fold them (especially to form
complex load / store addressing mode) when they have higher cost and
when they have more than one use.

86ecfda983 Refactor ARM STR/STRB instruction patterns into STR{B}i12 and STR{B}rs, like
the LDR instructions have. This makes the literal/register forms of the
instructions explicit and allows us to assign scheduling itineraries
appropriately. rdar://8477752

cdc8dff3ac SelectionDAG shuffle nodes do not allow operands with different numbers of
elements than the result vector type.  So, when an instruction like:

%8 = shufflevector <2 x float> %4, <2 x float> %7, <4 x i32> <i32 1, i32 0, i32 3, i32 2>

is translated to a DAG, each operand is changed to a concat_vectors node that appends 2 undef elements.  That is:

shuffle [a,b], [c,d] is changed to:
shuffle [a,b,u,u], [c,d,u,u]

That's probably the right thing for x86 but for NEON, we'd much rather have:

shuffle [a,b,c,d], undef

Teach the DAG combiner how to do that transformation for ARM.  Radar 8597007.

5d4415c6b0 The new LDR* instruction patterns should handle the necessary encoding of

e812b356cc Tweaks to X86 instructions to allow the 'w' suffix in places it makes
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler
allows for these instructions.  Done differently than in r117031 that
caused a valgrind error which was later reverted.

d5235bb45c Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc
will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

64680cd5b8 Change v64 datalayout in SPU.
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.
