2012-03-07  Richard Guenther  <rguenther@suse.de>

	* coverage.c (get_gcov_type): Use type_for_mode.
	(get_gcov_unsigned_t): Likewise.
	* expr.c (store_constructor): Use type_for_mode.
	(try_casesi): Likewise.
	* tree-ssa-loop-ivopts.c (add_standard_iv_candidates_for_size):
	Remove.
	(add_standard_iv_candidates): Use standard type trees.
	* dojump.c (do_jump): Remove dead code.
