Spoike 2158389bef Added IF_F instructions. 
Added -fassumeint so constants are by default ints instead of floats (like in C). Use a decimal point and it'll be a float.
Fixed a couple of omissions/bugs reported by Blub.
Added lame x86 jit which is still buggy, incomplete, and disabled. And bigfoot will hate it.
