glsl2: Teach copy propagation about "if" and "loop" instructions.
This lets us track copies across basic block boundaries. The loop doesn't get a filled out list of available copies into it yet, though. glsl-fs-raytrace drops from 585 to 535 Mesa IR instructions out of the compiler, and it appears that Yo Frankie's largest shaders decrease in Mesa IR count by about 10% as well.
