i965/fs: A little harmless refactoring of register_coalesce
Just pass the visitor into is_copy_payload() and is_coalesce_candidate()
instead of a register size and the virtual_grf_sizes array. Among other
things, this makes the code more obvious because you don't have to figure
out where src_size came from.
