Subject: tgsi: implement new float comparison instructions returning integer
 masks

Also while here add a bunch of other forgotten (integer) instructions to
tgsi_util_get_inst_usage_mask() (which isn't used for much except optimizing
away unused input components), though it may still be incomplete.
