kernel - pmap - more invltlb stuff

* Make sure pmap->pm_cache is cleared when a pmap gets reused,
  fixing an issue where the pmap subsystem wasn't properly
  invltlb'ing the recycled pmap due to stale cpu cache bits.

* Add sysctl vm.dreadful_invltlb (default to off) as a debugging aid.
  Turning this on disables pmap->pm_cache and does an unconditional
  invltlb on every pmap operation.
