Allow single-element interleaving for non-power-of-2 strides

This allows LD3 to be used for isolated a[i * 3] accesses, in a similar way to the current a[i * 2] and a[i * 4] for LD2 and LD4 respectively. Given the problems with the cost model underestimating the cost of elementwise accesses, the patch continues to reject the VMAT_ELEMENTWISE cases that are
