revset: make parents() O(number of parents)
Strip executes a revset like this:
max(parents(_intlist('1234\x001235')) - _intlist('1234\x001235'))
Previously the parents() revset would do 'subset & parents' which iterates over
each item in the subset and checks if it's in parents. subset is usually the
entire repo (a spanset) so this takes a while.
Reversing the parameters to be 'parents & subset' means the operation becomes
O(number of parents) instead of O(size of repo). It also means the result gets
evaluated immediately (since parents isn't a lazy set), but I think this is a
win in most scenarios.
This shaves 0.3 seconds off strip (amend/histedit/rebase/etc) for large repositories.
