[07/46] Add vec_info::lookup_stmt 

This patch adds a vec_info replacement for vinfo_for_stmt.  The main
difference is that the new routine can cope with arbitrary statements,
so there's no need to call vect_stmt_in_region_p first.

The patch only converts calls that are still needed at the end of the
series.  Later patches get rid of most other calls to vinfo_for_stmt.
