Optimize pmap_demote_pde() by using the new KPTmap to access a kernel
page table page instead of creating a temporary mapping to it.

Set the PG_G bit on the page table entries that implement the KPTmap.

Locore initializes the unused portions of the NKPT kernel page table
pages that it allocates to zero.  So, pmap_bootstrap() needn't zero
the page table entries referenced by CMAP1 and CMAP3.

Simplify pmap_set_pg().
