tree-vect-patterns.c (vect_pattern_recog_1): Add stmts_to_replace argument...
* tree-vect-patterns.c (vect_pattern_recog_1): Add stmts_to_replace
argument, truncate it at the beginning instead of allocating there
and freeing at the end.
(vect_pattern_recog): Allocate stmts_to_replace here and free at end,
pass its address to vect_pattern_recog_1.
