perf: add --reverse to perfrevlog

It can be useful to know how fast we can read revisions from a revlog
in reverse. This operation tends to occur in `hg log` commands,
for example.

#require test-repo pyflakes hg10

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ cd "`dirname "$TESTDIR"`"

run pyflakes on all tracked files ending in .py or without a file ending
(skipping binary file random-seed)

  $ hg locate 'set:**.py or grep("^#!.*python")' \
  > -X mercurial/pycompat.py \
  > 2>/dev/null \
  > | xargs pyflakes 2>/dev/null | "$TESTDIR/filterpyflakes.py"
