Log:
[44/46] Remove global vinfo_for_stmt-related routines

There are no more direct uses of:

- new_stmt_vec_info
- set_vinfo_for_stmt
- free_stmt_vec_infos
- free_stmt_vec_info

outside of vec_info, so they can now be private member functions.
It also seemed better to put them in tree-vectorizer.c, along with the
other vec_info routines.

We can also get rid of:

- vinfo_for_stmt
- stmt_vec_info_vec
- set_stmt_vec_info_vec

since nothing now uses them.  This was the main goal of the series.

	* tree-vectorizer.h (vec_info::new_vinfo_for_stmt)
	(vec_info::set_vinfo_for_stmt, vec_info::free_stmt_vec_infos)
	(vec_info::free_stmt_vec_info): New private member functions.

	(set_vinfo_for_stmt, new_stmt_vec_info, free_stmt_vec_info): Delete.
	* tree-parloops.c (gather_scalar_reductions): Remove calls to
	set_stmt_vec_info_vec and free_stmt_vec_infos.
	* tree-vect-loop.c (_loop_vec_info): Remove call to
	set_stmt_vec_info_vec.
	* tree-vect-stmts.c (new_stmt_vec_info, set_stmt_vec_info_vec)
	(free_stmt_vec_infos, free_stmt_vec_info): Delete in favor of...

	(vec_info::free_stmt_vec_info): ...these new functions.  Remove
	assignments in {vec_info::,}new_stmt_vec_info that are redundant
	with the clearing in the xcalloc.
	(stmt_vec_info_vec): Delete.
	(vec_info::vec_info): Don't call set_stmt_vec_info_vec.
	(vectorize_loops): Likewise.
	(vec_info::~vec_info): Remove argument from call to
	free_stmt_vec_infos.
	(vec_info::add_stmt): Remove vinfo argument from call to
	new_stmt_vec_info.
