f523e476c2 Revert r114703 and r114702, removing the isConditionalMove flag from instructions. After further 
reflection, this isn't going to achieve the purpose I intended it for.  Back to the drawing board!

1eb1b68e3a Fix an inconsistency in the x86 backend that led it to reject "calll foo" on 
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

b86faa17a4 reimplement support for GS and FS relative address space matching 
by having X86DAGToDAGISel::SelectAddr get passed in the parent node
of the operand match (the load/store/atomic op) and having it get
the address space from that, instead of having special FS/GS addr
mode operations that require duplicating the entire instruction set
to support.

This makes FS and GS relative accesses *far* more predictable and
work much better.  It also simplifies the X86 backend a bit, more
to come.

There is still a pending issue with nodes like ISD::PREFETCH and
X86ISD::FLD, which really should be MemSDNode's but aren't.

98f985607b Support all 128-bit AVX vector intrinsics. Most part of them I already 
declared during the addition of the assembler support, the additional
changes are:
- Add missing intrinsics
- Move all SSE conversion instructions in X86InstInfo64.td to the SSE.td file.
- Duplicate some patterns to AVX mode.
- Step into PCMPEST/PCMPIST custom inserter and add AVX versions.

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'.

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.
