[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.

gcc/
* tree-vectorizer.h (_stmt_vec_info::pattern_stmt_p): New field.
(is_pattern_stmt_p): Use it.
* tree-vect-patterns.c (vect_init_pattern_stmt): Set pattern_stmt_p
on pattern statements.
