    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.
