Add a few Subzero intrinsics (not the atomic ones yet).

Should I put "test_" prefix?

Keep it sorted?

I guess I have no real preference here (except to append with _Om1 / _O2).  And
there was no real consistency before. :)

Alright, I'll leave the filename alone for now, to keep review churn down, but
sort the tests after simple_loop.  Keep simple_loop first since that's the
simplest and if that doesn't work we're in trouble =)
