re PR tree-optimization/39129 (The meaning of 'BB' in "too many BBs in loop")

	PR tree-optimization/39129
	* 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".
	(vect_slp_analyze_bb, vect_slp_transform_bb): Likewise.
