194da7364d Added FMA3 Intel instructions. 
I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks.
I added tests for GodeGen and intrinsics.
I did not change llvm.fma.f32/64 - it may be done later.

0c823ae0ed Add intrinsics, code gen, assembler and disassembler support for the SSE4a extrq and insertq instructions. 
This required light surgery on the assembler and disassembler
because the instructions use an uncommon encoding. They are
the only two instructions in x86 that use register operands
and two immediates.

2e62e2f664 Allow MCCodeEmitter access to the target MCRegisterInfo. 
Add the MCRegisterInfo to the factories and constructors.

82af1c8704 Fix generation of the address size override prefix. Add assertions for 
the invalid cases. At least 16bit operand in 64bit mode is currently not
rejected in the parser.

44a5136fac Separate the concept of having memory access in operand 4 from the concept of having the W bit set for XOP instructons. Removes ORing W-bits in the encoder and will similarly simplify the disassembler implementation.

9b9d35cc05 Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas 
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

626d04cc6f This patch contains support for encoding FMA4 instructions and 
tablegen patterns for scalar FMA4 operations and intrinsic. Also
add tests for vfmaddsd.

4c6357d4af Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand 3 instead of Operand 2 so needs special casing in the disassembler and code emitter. Ultimately, should pass this information from tablegen

62e63d9bb9 Add support for X86 blsr, blsmsk, and blsi instructions. Required extra work because these are the first VEX encoded instructions to use the reg field as an opcode extension.

04762a3cf5 Emit an error is asm parser parsed X86_64 only registers, e.g. %rax, %sil. 
This can happen in cases where TableGen generated asm matcher cannot check
whether a register operand is in the right register class. e.g. mem operands.
