Currently unimplemented:
* cast fp to bool
* signed right shift
Current bugs:
* use of a cByte/cShort by setCC not first truncated or sign extended
(uByte r3 = 250, r3 + 100; setlt r3, 200 will get wrong result).
* conditional branches assume target is within 32k bytes
* large fixed-size allocas not correct
Currently failing tests:
* Regression
* SingleSource
