alc f2b4bbab1c Use pmap_enter(..., psind=1) in vm_fault_populate() on amd64. While
superpage mappings were already being created by automatic promotion in
vm_fault_populate(), this change reduces the cost of creating those
mappings.  Essentially, one pmap_enter(..., psind=1) call takes the place
of 512 pmap_enter(..., psind=0) calls, and that one pmap_enter(...,
psind=1) call eliminates the allocation of a page table page.
