perf: add perffncacheencode

Examples (all done with somewhat dated clones I found on my disk):

Netbeans (~120k entries in fncache):

  $ hg perffncacheencode
  ! wall 4.338000 comb 4.336828 user 4.336828 sys 0.000000 (best of 3)

Openoffice (~77k entries in fncache)):

  $ hg perffncacheencode
  ! wall 1.533000 comb 1.528810 user 1.528810 sys 0.000000 (best of 7)

Xen (~10k entries in fncache):

  $ hg perffncacheencode
  ! wall 0.198000 comb 0.187201 user 0.187201 sys 0.000000 (best of 51)

Done on Windows 7 x64.
