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

	* omp-low.c (extract_omp_for_data): Use signed_type_for.
	(expand_omp_for_generic): Likewise.
	(expand_omp_for_static_nochunk): Likewise.
	(expand_omp_for_static_chunk): Likewise.
	* tree-vect-stmts.c (vect_gen_perm_mask): Use type_for_mode.
	* tree-vect-slp.c (vect_transform_slp_perm_load): Likewise.
	* tree-vect-loop-manip.c (vect_gen_niters_for_prolog_loop):
	Use unsigned_type_for.
	(vect_create_cond_for_align_checks): Use signed_type_for.
