Added files:

Log message:
	* tree-vectorizer.c (new_loop_vec_info): Initialize
	LOOP_VINFO_MAY_MISALIGN_STMTS.
	(destroy_loop_vec_info); varray_clear of LOOP_VINFO_MAY_MISALIGN_STMTS.
	(vect_create_cond_for_align_checks): New function.
	(vect_transform_loop): Add calls to tree_ssa_loop_version and
	vect_create_cond_for_align_checks.
	(vect_build_dist_vector): Change loop_info to loop_vinfo as it is
	called elsewhere.
	(vect_update_misalignment_for_peel): New function.
	(vect_enhance_data_refs_alignment): Decide when to do loop
	versioning and update data structcures.
	(vect_analyze_data_refs_alignment): Fix comment.
	(vect_pattern_recog): Fix comment.
	(vectorize_loops): Tmporarily move call to rewrite_into_loop_closed_ssa
	so it's done each time it's needed rather than once at the end.
	(vect_verify_datarefs_alignment): New function.
	* tree-vectorizer.h (struct _loop_vec_info): Add fields ptr_mask and
	may_misalign_stmts.
	(MAX_RUNTIME_ALIGNMENT_CHECKS): New named constant.
