Many of these are simply aliases for other instructions, though I do see a missing implementation of test_mm_comige_ss (ironically, test_mm_comigt_ss actually uses _mm_comige_ss)

Would we want to duplicate these tests? Either that, or indicate to functions! somehow that an instruction is aliased, so the checker doesn't give false positives.

I imagine duplicating the tests would be as simple as calling the alias's test function, or turning it into a macro that expands into the two versions.
