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.
