* tree-vectorizer.h (struct dataref_aux): Add base_element_aligned
field.
(DR_VECT_AUX): New macro.
(set_dr_misalignment): Adjust.
(dr_misalignment): Likewise.
* tree-vect-data-refs.c (vect_compute_data_ref_alignment):
Compute whether the base is at least element aligned.
* tree-vect-stmts.c (ensure_base_align): Adjust.
(vectorizable_store): If the base is not element aligned
preserve alignment of the original access if misalignment is unknown.
(vectorizable_load): Likewise.
