x86-64: honor REX prefixes for SSE2AVX

Legacy encoded insns do so, and their automatic conversion to AVX ones
ought to produce functionally identical code. Therefore explicit REX
prefixes cannot simply be ignored. This is in particular relevant
because at least PCMPESTR{I,M}'s 64-bit forms couldn't be expressed in
older gas by other than using a REX64 prefix.
