        src/sys/arch/x86/include: pmap.h
        src/sys/arch/x86/x86: pmap.c x86_tlb.c
        src/sys/dev/nvmm/x86: nvmm_x86_svm.c nvmm_x86_vmx.c

Log Message:
x86 pmap:

- Give pmap_remove_all() its own version of pmap_remove_ptes() that on native
  x86 does the bare minimum needed to clear out PTPs.  Cuts ~4% sys time on
  'build.sh release' for me.

- pmap_sync_pv(): there's no need to issue a redundant TLB shootdown.  The
  caller waits for the competing operation to finish.

- Bring 'options TLBSTATS' up to date.
