revset: cache most conditions used in `filter`
Except when stated otherwise, the condition used in `smartset.filter` will be
cached. A new argument has been introduced to disable that behavior. We use it
for filters created from `and` and `sub` operations.
This gives massive performance boosts for revsets with expensive conditions.
