perf: add perfmoonwalk command to walk the changelog backwards
This lets us test the effectiveness (or ineffectiveness) of the revlog chunk
cache when walking revlogs backwards.
$ echo "[extensions]" >> $HGRCPATH
$ echo "largefiles =" >> $HGRCPATH
Create the repository outside $HOME since largefiles write to
$HOME/.cache/largefiles.

Systematic testing of merges involving largefiles:
Ancestor: normal Parent: normal= Parent: large result: large
Ancestor: normal Parent: normal2 Parent: large result: ?
Ancestor: large Parent: large= Parent: normal result: normal
Ancestor: large Parent: large2 Parent: normal result: ?
All cases should try merging both ways.
"=" means same file content.
Prepare test repo:
