setcc() in math-emu is written as a gcc extension statement expression macro that returns a value. However, it's not used that way and it's not needed like that, so just make it a do-while non-extension macro so that we don't use an extension when it's not needed.

... seems to contradict the implementation. No "do-while" here.
