Craig Topper ed7aa46366 Add X86 assembler and disassembler support for AMD SVM instructions. Original patch by Kay Tiong Khoo. Few tweaks by me for code density and to reduce replication.

Craig Topper cd93de93fa 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.

Rafael Espindola c7f355b8e1 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.

Jan Sjödin d19760a40c Src2 and src3 were accidentally swapped for the FMA4 rr patterns. Undo this and fix the encoding.

Bruno Cardoso Lopes 0f9a1f5e6c This patch contains support for encoding FMA4 instructions and
tablegen patterns for scalar FMA4 operations and intrinsic. Also
add tests for vfmaddsd.

Craig Topper 25ea4e5ad3 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

Craig Topper 27ad12539d 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.

Evan Cheng eda1d4f3ba 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.
