X86: Implement movd_Vo_Edp on X86

This patch implements the movd_Vo_Edp series of instructions.

It addresses various concerns by Gabe Black about which file the
instruction belonged in, as well as supporting REX prefixed
instructions properly.

This instruction is needed for some of the spec2k benchmarks, most
notably bzip2.
