[x64] Fix the assembler and the disassembler.

[x64] Small fixes in the assembler and disassembler.

Disassembler:
added decoding of a few instructions that were previously unsupported, fixed the decoding of pextr.

Assembler:

pmulld(XMMRegister, Operand) was actually emitting a pmuludq.

punpckldq(XMMRegister, XMMRegister) was implemented a second time as punpackldq.
