perf: update perfindex to be more realistic

The previous code was creating a revlog manually, we now use the actual
`localrepo` method to create it.

We have to jump though extra hops to work around the impact of filecache.

Tests rebasing with part of the rebase set already in the
destination (issue5422)

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase=
  > drawdag=$TESTDIR/drawdag.py
  > 
  > [experimental]
  > evolution.createmarkers=True
  > evolution.allowunstable=True
  > 
  > [alias]
  > tglog = log -G --template "{rev}: {node|short} {desc}"
  > EOF

  $ rebasewithdag() {
  >   N=`"$PYTHON" -c "print($N+1)"`
  >   hg init repo$N && cd repo$N
  >   hg debugdrawdag
  >   hg rebase "$@" > _rebasetmp
  >   r=$?
  >   grep -v 'saved backup bundle' _rebasetmp
  >   [ $r -eq 0 ] && hg tglog
  >   cd ..
  >   return $r
  > }

Rebase two commits, of which one is already in the right place

  $ rebasewithdag -r C+D -d B <<EOF
  > C
  > |
  > B D
  > |/
  > A
  > EOF
  rebasing 2:b18e25de2cf5 "D" (D)
  already rebased 3:26805aba1e60 "C" (C tip)

  | o  3: 26805aba1e60 C

  o |  1: 112478962961 B

Can collapse commits even if one is already in the right place

  $ rebasewithdag --collapse -r C+D -d B <<EOF
  > C
  > |
  > B D
  > |/
  > A
  > EOF
  rebasing 2:b18e25de2cf5 "D" (D)

  o |  1: 112478962961 B

Abort doesn't lose the commits that were already in the right place

  $ hg init abort
  $ cd abort
  $ hg debugdrawdag <<EOF
  > C
  > |
  > B D  # B/file = B
  > |/   # D/file = D
  > A
  > EOF
  $ hg rebase -r C+D -d B
  rebasing 2:ef8c0fe0897b "D" (D)
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see hg resolve, then hg rebase --continue)
  [1]
  $ hg rebase --abort
  rebase aborted
  $ hg tglog
  o  3: 79f6d6ab7b14 C

  $ cd ..

Rebase with "holes". The commits after the hole should end up on the parent of
the hole (B below), not on top of the destination (A).

  $ rebasewithdag -r B+D -d A <<EOF
  > D
  > |
  > C
  > |
  > B
  > |
  > A
  > EOF
