revset: handle wdir() in `sort(..., -topo)`
The last apparent usage of `repo.changelog.parentrevs` in revsets is in
`children()`, but since the sets being operated on never include wdir(), it's
never called with `wdirrev` and the wdir() arg on the command line is
effectively ignored instead of aborting there. I'm not sure how to fix that.
Before (on a clone of hg):
$ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'sort(all(), -topo)'
! wall 0.123663 comb 0.130000 user 0.130000 sys 0.000000 (best of 76)
After:
$ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'sort(all(), -topo)'
! wall 0.123838 comb 0.130000 user 0.130000 sys 0.000000 (best of 75)
