Make record_dead_and_set_regs return after processing a CALL_INSN,
rather than recording that r3 is set from a call pattern.
Also, that should really be using regs_invalidated_by_call rather
than call_used_regs. Not that it'll make too much difference,
since we don't do a whole lot of combining with fixed registers.
