    x86: Also require MMX for __builtin_ia32_maskmovq

    MMX emulation with SEE is implemented at MMX intrinsic level, not at MMX
    instruction level.  _mm_maskmove_si64 intrinsic for "MASKMOVQ mm1, mm2"
    is emulated with __builtin_ia32_maskmovdqu.  Since SSE "MASKMOVQ mm1, mm2"
    builtin function, __builtin_ia32_maskmovq, can't be emulated with XMM
    registers, make __builtin_ia32_maskmovq also require MMX instead of SSE
    only.
