    x86: adjust MOVSD attributes
    
    The non-SSE2AVX form of the SIMD variant of the instruction needlessly
    has the (still multi-purpose) IgnoreSize attribute. All other similar
    SSE2 insns use NoRex64 instead. Make this consistent, noting that the
    SSE2AVX form can't have the same change made - there the memory operand
    doesn't at the same time permit RegXMM (which logic uses when deciding
    whether a Q suffix is okay outside of 64-bit mode).
