- added an optimization to FxBoolCast that it doesn't force the source value to a 0/1 integer if not explicitly needed. When doing comparisons we do not care about actual values, we only want to know if it is 0 or not.

- added the above for the 'if' condition. It works for integers, floats and pointers and will save 3 instructions if the condition is a non-boolean that can be implicitly casted to bool.
