loop.c (scan_loop, [...]): Cast to avoid signed/unsigned warnings.

	* loop.c (scan_loop, move_movables, count_one_set): Cast to avoid
	signed/unsigned warnings.

	* regclass.c (init_reg_sets_1, choose_hard_reg_mode,
	record_reg_classes): Likewise.

	* reload.c (reload_inner_reg_of_subreg, push_reload,
	find_reloads_address_1): Likewise.
