9a9d275dc7 Custom lower the memory barrier instructions and add support
for lowering without sse2.  Add a couple of new testcases.

Fixes a few libgomp tests and latent bugs.  Remove a few todos.

to the libcall not existing.

77e2dd7bb2 X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

e86b01c153 Start the support for AVX instructions with 256-bit %ymm registers. A couple of
notes:
- The instructions are being added with dummy placeholder patterns using some 256
  specifiers, this is not meant to work now, but since there are some multiclasses
  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.

c5f5626a29 have the mc lowering process handle a few tail call forms, lowering them to
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.

This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.

599b531a96 Change LEA to have 5 operands for its memory operand, just
like all other instructions, even though a segment is not
allowed.  This resolves a bunch of gross hacks in the 
encoder and makes LEA more consistent with the rest of the
instruction set.

No functionality change.

a938cfb13a Finish ripping isTwoAddress out of X86. Some mindless formatting

The giant turn the constraints on and selectively turn it off

50/50.

addw $0xFFFF, %ax
should match the same as
  addw $-1, %ax
but we used to match it to the longer encoding.

3c979b06c0 Fixed the encoding of the x86 push instructions. Using a 32-bit immediate value
caused the a pushl instruction to be incorrectly encoding using only two bytes
of immediate, causing the following 2 instruction bytes to be part of the 32-bit
immediate value.  Also fixed the one byte form of push to be used when the
immediate would fit in a signed extended byte.  Lastly changed the names to not
include the 32 of PUSH32 since they actually push the size of the stack pointer.
