thorpej c7b8439ec4 - Make lazy I-sync a little safer -- always mark the pmap as needing 
I-sync in pmap_remove_mapping() if the old mapping had PG_EXEC, and
  kick curcpu (IMB) or other CPUs (via an IPI) only if the pmap was
  the kernel pmap or active on other CPUs (curcpu is handled in userret()).
- Use lazy I-sync everywhere, (hopefully) eliminating the last of the
  I-sync issues for multiprocessor support.
- Eliminate some memory barriers added in a couple of previous revisions,
  after some discussion on port-alpha/tech-smp.

Still some lazy I-sync optimization possibilites:
- pmap_changebit() does not need to I-sync when only write-protecting
  a page.
- pmap_asn_alloc() may be able to cancel a pending lazy I-sync when a
  new ASN is allocated.  Need to double check against Green Book or
  Brown Book.
