graphlog: pass changesets to revset.match() in changelog order

Running:

  $ time hg debugrevspec 'user(mpm)' | wc

on Mercurial repository takes 1.0s with a regular version and 1.8s if
commands.debugrevspec() is patched to pass revisions to revset.match() from tip
to 0.

Depending on what we expect from the revset API and caller wisdom, we might
want to push this change in revset.match() later.

b51a8138292a introduced a regression where we would mention in the
changelog executable files added by the second parent of a merge. Test
that that doesn't happen anymore

  $ "$TESTDIR/hghave" execbit || exit 80

  $ hg init repo
  $ cd repo
  $ echo foo > foo
  $ hg ci -qAm 'add foo'

  $ echo bar > bar
  $ chmod +x bar
  $ hg ci -qAm 'add bar'

manifest of p2:

  $ hg manifest
  bar
  foo

  $ hg up -qC 0
  $ echo >> foo
  $ hg ci -m 'change foo'
  created new head

manifest of p1:

  $ hg manifest
  foo

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m 'merge'

this should not mention bar:

  $ hg tip -v
