re PR tree-optimization/43074 (ICE in vectorizable_reduction, at tree-vect-loop.c:3491)
PR tree-optimization/43074
* tree-vectorizer.h (VECTORIZABLE_CYCLE_DEF): New.
* tree-vect-loop.c (vect_analyze_loop_operations): Add
vectorizable cycles in hybrid SLP check.
* tree-vect-slp.c (vect_detect_hybrid_slp_stmts): Likewise.
