i965/vec4: Compare full register offsets in cmod propagation.

Cmod propagation would misoptimize the program if the destination
offset of the generating instruction wasn't exactly the same as the
source region offset of the copy instruction.  In preparation for
adding support for sub-GRF offsets to the VEC4 IR.
