        PR target/84335
        * config/i386/i386.c (ix86_init_mmx_sse_builtins): Pass
        OPTION_MASK_ISA_AES | OPTION_MASK_ISA_SSE2 instead of
        OPTION_MASK_ISA_AES as first argument to def_builtin_const
        for AES builtins.  Pass OPTION_MASK_ISA_PCLMUL | OPTION_MASK_ISA_SSE2
        instead of OPTION_MASK_ISA_PCLMUL as first argument to
        def_builtin_const for __builtin_ia32_pclmulqdq128 builtin.
        * config/i386/wmmintrin.h: If __SSE2__ is not defined, enable it
        temporarily for AES and PCLMUL builtins.

        * gcc.target/i386/pr84335.c: New test.
