(cse_and_gimplify_to_preheader): Declare. (vect_get_place_in_interleaving_chain): Likewise. * tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Initialize ivexpr_map. (_loop_vec_info::~_loop_vec_info): Delete it. (cse_and_gimplify_to_preheader): New function. * tree-vect-slp.c (vect_get_place_in_interleaving_chain): Export. * tree-vect-stmts.c (vectorizable_store): CSE base and steps. (vectorizable_load): Likewise. For grouped stores always base the IV on the first element. * tree-vect-loop-manip.c (vect_loop_versioning): Unshare versioning condition before gimplifying.
