[06/46] Add vec_info::add_stmt

This patch adds a vec_info function for allocating and setting
stmt_vec_infos.  It's the start of a long process of removing
the global stmt_vec_info array.

	* tree-vectorizer.h (stmt_vec_info): Move typedef earlier in file.
	(vec_info::add_stmt): Declare.
	* tree-vectorizer.c (vec_info::add_stmt): New function.
	* tree-vect-data-refs.c (vect_create_data_ref_ptr): Use it.
	* tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Likewise.
	(vect_create_epilog_for_reduction, vectorizable_reduction): Likewise.
	(vectorizable_induction): Likewise.
	* tree-vect-slp.c (_bb_vec_info::_bb_vec_info): Likewise.

	(vect_recog_bool_pattern, vect_recog_mask_conversion_pattern)
	(vect_recog_gather_scatter_pattern): Likewise.
	(append_pattern_def_seq): Likewise.  Remove a check that is
	performed by add_stmt itself.
