PR tree-optimization/52298
* tree-vect-stmts.c (vectorizable_store): Properly use
STMT_VINFO_DR_STEP instead of DR_STEP when vectorizing
outer loops.
(vectorizable_load): Likewise.
* tree-vect-data-refs.c (vect_analyze_data_ref_access):
Access DR_STEP after ensuring it is not NULL.
* gcc.dg/torture/pr52298.c: New testcase.
* gcc.dg/vect/pr52298.c: Likewise.
