i965/vec4: Assign correct destination offset to rewritten instruction in register coalesce.
Because the pass already checks that the destination offset of each 'scan_inst' that needs to be rewritten matches 'inst->src[0].offset' exactly, the final offset of the rewritten instruction is just the original destination offset of the copy. This is in preparation for adding support for sub-GRF offsets to the VEC4 IR. Reviewed-by: Iago Toral Quiroga <[email protected]>
