node: define experimental identifiers for working directory

The "ff..." node was introduced at 183965a00c76, and we also need an integer
that can be processed in revset. We could use len(repo), but it would be
likely to hide possible bugs. Instead, using INT_MAX, we can notice such bugs
by IndexError, at the cost of handling non-contiguous revisions.
