tree-vectorizer.h (struct _stmt_vec_info): Add new field for pattern def statement, and its access macro.
* tree-vectorizer.h (struct _stmt_vec_info): Add new field for
pattern def statement, and its access macro.
(NUM_PATTERNS): Set to 5.
* tree-vect-loop.c (vect_determine_vectorization_factor): Handle
pattern def statement.
(vect_transform_loop): Likewise.
* tree-vect-patterns.c (vect_vect_recog_func_ptrs): Add new
function vect_recog_over_widening_pattern ().
(vect_operation_fits_smaller_type): New function.
(vect_recog_over_widening_pattern, vect_mark_pattern_stmts):
Likewise.
(vect_pattern_recog_1): Move the code that marks pattern
statements to vect_mark_pattern_stmts (), and call it. Update
documentation.
* tree-vect-stmts.c (vect_supportable_shift): New function.
(vect_analyze_stmt): Handle pattern def statement.
(new_stmt_vec_info): Initialize pattern def statement.
