discovery: cache the children mapping used during each discovery
During discovery, the `undecided` set keep shrinking. Therefore, the map
computed for an iteration N will be valid for iteration N+1. Instead of
computing the same data over and over we cache it the first time.
Our private pathological case speed up from about 7.5 seconds to about 6.3
seconds.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
