Alan Cox 3fc10b7363 Introduce vm_radix_isleaf() and use it in a couple places. As compared to
using vm_radix_node_page() == NULL, the compiler is able to generate one
less conditional branch when vm_radix_isleaf() is used.  More use cases
involving the inner loops of vm_radix_insert(), vm_radix_lookup{,_ge,_le}(),
and vm_radix_remove() will follow.
