[qfcc] Correct swizzle expressions
It turned out they were always using floats for the source type (meaning doubles were broken), and not shifting the component in the final sizzle code meaning all swizzles were ?xxx (neglecting minus or 0). I'd make tests, but I plan on modifying the instruction set a little bit.
