[Bug target/40957] standard_sse_constant_opcode crash on x86 64

We enter standard_sse_constant_opcode with:

(const_vector:V4DI [
        (const_int -1 [0xffffffffffffffff])
        (const_int -1 [0xffffffffffffffff])
        (const_int -1 [0xffffffffffffffff])
        (const_int -1 [0xffffffffffffffff])
    ])

And standard_sse_constant_p returns 3 in this case.

H.J., can this operation be implemented with AVX vcmpeq instruction?
