[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.
