PR tree-optimization/91822
* tree-vectorizer.h (vectorizable_condition): Restore for_reduction
parameter.
* tree-vect-loop.c (vectorizable_reduction): Adjust asserts
for reduc_index in nested cycles, adjust vectorizable_condition
calls.
* tree-vect-stmts.c (vectorizable_condition): Restore for_reduction
parameter.
(vect_analyze_stmt): Adjust.
(vect_transform_stmt): Likewise.
