When we determine overrun we have to consider VMAT_CONTIGUOUS_REVERSE
the same as VMAT_CONTIGUOUS.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

	PR tree-optimization/115741
	* tree-vect-stmts.cc (get_group_load_store_type): Also
	handle VMAT_CONTIGUOUS_REVERSE when determining overrun.
