* tree-vect-slp.c (vect_slp_analyze_bb_1): Delay call to
vect_verify_datarefs_alignment until after statements have
been marked as relevant/irrelevant.
* tree-vect-data-refs.c (vect_verify_datarefs_alignment):
Skip irrelevant statements.
(vect_enhance_data_refs_alignment): Use STMT_VINFO_RELEVANT_P
instead of STMT_VINFO_RELEVANT.
(vect_get_data_access_cost): Do not check for supportable
alignment before calling vect_get_load_cost/vect_get_store_cost.
* tree-vect-stmts.c (vect_get_store_cost): Do not abort when
handling unsupported alignment.
(vect_get_load_cost): Likewise.
