  Log:
  Restructure vm_page_select_cache() so that adding assertions is easy.
  
  Some of the conditions that caused vm_page_select_cache() to deactivate a
  page were wrong.  For example, deactivating an unmanaged or wired page is a
  nop.  Thus, if vm_page_select_cache() had ever encountered an unmanaged or
  wired page, it would have looped forever.  Now, we assert that the page is
  neither unmanaged nor wired.
