[14/46] Make STMT_VINFO_VEC_STMT a stmt_vec_info

This patch changes STMT_VINFO_VEC_STMT from a gimple stmt to a
stmt_vec_info and makes the vectorizable_* routines pass back
a stmt_vec_info to vect_transform_stmt.

gcc/
	* tree-vectorizer.h (_stmt_vec_info::vectorized_stmt): Change from
	a gimple stmt to a stmt_vec_info.
	(vectorizable_condition, vectorizable_live_operation)
	(vectorizable_reduction, vectorizable_induction): Pass back the
	vectorized statement as a stmt_vec_info.
	* tree-vect-data-refs.c (vect_record_grouped_load_vectors): Update
	use of STMT_VINFO_VEC_STMT.
	* tree-vect-loop.c (vect_create_epilog_for_reduction): Likewise,
	accumulating the inner phis that feed the STMT_VINFO_VEC_STMT
	as stmt_vec_infos rather than gimple stmts.
	(vectorize_fold_left_reduction): Change vec_stmt from a gimple stmt
	to a stmt_vec_info.
	(vectorizable_live_operation): Likewise.
	(vectorizable_reduction, vectorizable_induction): Likewise,
	updating use of STMT_VINFO_VEC_STMT.
	* tree-vect-stmts.c (vect_get_vec_def_for_operand_1): Update use
	of STMT_VINFO_VEC_STMT.
	(vect_build_gather_load_calls, vectorizable_bswap, vectorizable_call)
	(vectorizable_simd_clone_call, vectorizable_conversion)
	(vectorizable_assignment, vectorizable_shift, vectorizable_operation)
	(vectorizable_store, vectorizable_load, vectorizable_condition)
	(vectorizable_comparison, can_vectorize_live_stmts): Change vec_stmt
	from a gimple stmt to a stmt_vec_info.
	(vect_transform_stmt): Update use of STMT_VINFO_VEC_STMT.  Pass a
	pointer to a stmt_vec_info to the vectorizable_* routines.
