mesa: Add channel-wise copy propagation to ir_to_mesa.

This catches more opportunities than the prog_optimize.c code on
openarena's fixed function shaders turned to GLSL, mostly due to
looking at multiple source instructions for copy propagation
opportunities.  It should also be much more CPU efficient than
prog_optimize.c's code.
