tree-optimization/115741 - ICE with VMAT_CONTIGUOUS_REVERSE and gap
When we determine overrun we have to consider VMAT_CONTIGUOUS_REVERSE
the same as VMAT_CONTIGUOUS.
PR tree-optimization/115741
* tree-vect-stmts.cc (get_group_load_store_type): Also
handle VMAT_CONTIGUOUS_REVERSE when determining overrun.
