        * tree-vect-loop-manip.c (conservative_cost_threshold): Change the 
        printed message.
        (vect_do_peeling_for_loop_bound): Use 
        LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT and
        LOOP_REQUIRES_VERSIONING_FOR_ALIAS macros.
        (vect_loop_versioning): Likewise.
        (vect_create_cond_for_alias_checks): Fix indentation.
        * tree-vectorizer.h (struct _loop_vec_info): Fix indentation of the 
        macros.
        (LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT): Define.
        (LOOP_REQUIRES_VERSIONING_FOR_ALIAS): Likewise.
        * tree-vect-loop.c (vect_analyze_loop_form): Change "too many BBs" to 
        "control flow in loop".
        (vect_estimate_min_profitable_iters): Use 
        LOOP_REQUIRES_VERSIONING_FOR_ALIGNMENT and
        LOOP_REQUIRES_VERSIONING_FOR_ALIAS macros.
        * tree-vect-data-refs.c (vect_enhance_data_refs_alignment): Likewise.
        (vect_create_data_ref_ptr): Don't mention array dimension in printing.
        * tree-vect-stmts.c (vectorizable_store): Replace the check that the 
        statement belongs to a group of strided accesses with the exact code 
        check.
        (vectorizable_load): Likewise.
        * tree-vect-slp.c (vect_analyze_slp_instance): Spell out "basic block".
