        * config/i386/i386.c (ix86_init_mmx_sse_builtins): Add
        OPTION_MASK_ISA_MMX for __builtin_ia32_maskmovq,
        __builtin_ia32_vec_ext_v4hi and __builtin_ia32_vec_set_v4hi.
        (ix86_expand_builtin): Treat OPTION_MASK_ISA_MMX similarly
        to OPTION_MASK_ISA_AVX512VL - builtins that have both
        OPTION_MASK_ISA_MMX and some other bit set require both
        mmx and the ISAs without the mmx bit.

        __builtin_ia32_paddq, __builtin_ia32_psubq, __builtin_ia32_palignr):
        Add OPTION_MASK_ISA_MMX.
