[45/46] Remove vect_stmt_in_region_p 

Unlike the old vinfo_for_stmt, vec_info::lookup_stmt can cope with
any statement, so there's no need to check beforehand that the statement
is part of the vectorisable region.  This means that there are no longer
any calls to vect_stmt_in_region_p.

gcc/
	* tree-vectorizer.h (vect_stmt_in_region_p): Delete.
	* tree-vectorizer.c (vect_stmt_in_region_p): Likewise.
