Actually, hold-off on reviewing. I don't think the logic for sign extension is correct when the target memory location isn't 32-bit aligned. Sorry for the noise. I'll add look again and add more tests to cover this.

It's a little tempting to just fail for [u]min/max of i8/i16 given Clang never generates them, but we've got this far now...
