rust-index: improve phase computation speed
While less memory efficient, using an array is *much* faster than using a
HashMap, especially with the default hasher. It even makes the code simpler,
so I'm not really sure what I was thinking in the first place, maybe it's more
obvious now.
This fix a significant performance regression when using the rust version of the
code. (however, the C code still outperform rust on this operation)

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).
