        PR target/79568
        * config/i386/i386.c (ix86_expand_builtin): Handle
        OPTION_MASK_ISA_AVX512VL and OPTION_MASK_ISA_64BIT in
        ix86_builtins_isa[fcode].isa as a requirement of those
        flags and any other flag in the bitmask.
        (ix86_init_mmx_sse_builtins): Use 0 instead of
        ~OPTION_MASK_ISA_64BIT as mask.
        * config/i386/i386-builtin.def (bdesc_special_args,
        bdesc_args): Likewise.

        * gcc.target/i386/pr79568-1.c: New test.
        * gcc.target/i386/pr79568-2.c: New test.
        * gcc.target/i386/pr79568-3.c: New test.
