mesa/program: Don't copy propagate from swizzles.
Do not propagate a copy if source and destination are identical.
Otherwise code like
MOV TEMP[0].xyzw, TEMP[0].wzyx
MOV TEMP[1].xyzw, TEMP[0].xyzw
is changed to
MOV TEMP[0].xyzw, TEMP[0].wzyx
MOV TEMP[1].xyzw, TEMP[0].wzyx
This fixes Piglit test shaders/glsl-copy-propagation-self-2 for drivers that
use Mesa IR.
NOTE: This is a candidate for the stable branches.
