perf: fix perfrevlogrevisions --reverse

Currently, 'endrev' equals `len(revlog)`, a revision that does not exist.

When asking for the reverse order, the arguments passed to xrange are
`xrange(len(revlog), startrev)` which then crash.

We need to offset 'endrev' by one so we don't crash anymore. Also, we offset
'startrev' to ensure we get the same number of revisions with and without the
`--reverse` option.

#require no-reposimplestore

Testing the case when there is no infinitepush extension present on the client
side and the server routes each push to bundlestore. This case is very much
similar to CI use case.

Setup
-----

  $ . "$TESTDIR/library-infinitepush.sh"
  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > ssh = python "$TESTDIR/dummyssh"
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc}\n{phase}"
  > EOF
  $ cp $HGRCPATH $TESTTMP/defaulthgrc
  $ hg init repo
  $ cd repo
  $ setupserver
  $ echo "pushtobundlestore = True" >> .hg/hgrc
  $ echo "[extensions]" >> .hg/hgrc
  $ echo "infinitepush=" >> .hg/hgrc
  $ echo initialcommit > initialcommit
  $ hg ci -Aqm "initialcommit"
  $ hg phase --public .

  $ cd ..
  $ hg clone repo client -q
  $ hg clone repo client2 -q
  $ hg clone ssh://user@dummy/repo client3 -q
  $ cd client

Understanding how data is stored on the bundlestore in server
-------------------------------------------------------------

There are two things, filebundlestore and index
  $ ls ../repo/.hg/scratchbranches
  filebundlestore
  index

filebundlestore stores the bundles
  $ ls ../repo/.hg/scratchbranches/filebundlestore/a4/c2/
  a4c202c147a9c4bb91bbadb56321fc5f3950f7f2

index/nodemap stores a map of node id and file in which bundle is stored in filebundlestore
  $ ls ../repo/.hg/scratchbranches/index/
  nodemap
  $ ls ../repo/.hg/scratchbranches/index/nodemap/
  6cb0989601f1fb5805238edfb16f3606713d9a0b

  $ cd ../repo
