[36/46] Add a pattern_stmt_p field to stmt_vec_info

This patch adds a pattern_stmt_p field to stmt_vec_info, so that it's
possible to tell whether the statement is a pattern statement without
referring to other statements.  The new field goes in what was
previously a hole in the structure, so the size is the same as before.
