Log Message:
add a new flag VM_MAP_DYING, which is set before we start
tearing down a vm_map.  use this to skip the pmap_update()
at the end of all the removes, which allows pmaps to optimize
pmap tear-down.  also, use the new pmap_remove_all() hook to
let the pmap implemenation know what we're up to.
