	* tree-vect-slp.c (vect_find_first_load_in_slp_instance): Remove.
	(vect_find_last_store_in_slp_instance): Rename to ...
	(vect_find_last_scalar_stmt_in_slp): ... this and generalize.
	(vect_analyze_slp_cost_1): Use vector_load for constant defs
	and vec_construct for external defs when estimating prologue cost.
	(vect_analyze_slp_instance): Do not init SLP_INSTANCE_FIRST_LOAD_STMT.
	Compute costs here only when vectorizing loops.
	(vect_slp_analyze_bb_1): Compute SLP cost here, after vector types
	have been determined.
	(vect_schedule_slp_instance): Simplify vectorized code placement
	and prepare for in-BB external defs.
	* tree-vectorizer.h (struct _slp_instance): Remove first_load member.
	(SLP_INSTANCE_FIRST_LOAD_STMT): Remove.
	* tree-vect-stmts.c (vect_model_store_cost): Remove PURE_SLP_STMT
	guard.
	(vect_model_load_cost): Likewise.
	(vectorizable_store): Instead add it here.
	(vectorizable_load): Likewise.
	(vect_is_simple_use): Dump def type textually.
