Summary SuperRegion doesn't call deallocate() on its PageReservation

It should. This doesn't cause us to leak physical memory, but it does cause us to leak virtual address space (and probably mach ports), which is also bad :-( FixedVMPoolExecutableAllocator also has this bug, but it doesn't matter much because there's only one instance of that class throughout the entire lifetime of the process, whereas each VM has its own SuperRegion.
