Add a relation table for Revisions to local commit hashes
Summary:
This allows us to performantly query for diffs related to a given local hash.
Immediate applications are:
- Commit detection in Mercurial and Git-Immutable workflows.
- Some async unit test stuff @mgummelt was doing.
Test Plan:
Diffed locally under SVN/Git/hg, checked the table, got sensible output.

NOTE: Mercurial hashes are short-form but I'll shoot out a separate Arcanist
diff to fix this.
