Display number of invalidations per query

[Aaron1011]

Slowdowns in incremental benchmarks can often be due to increased query invalidation (adding extra query dependency edges, or making a stable hash dependent on more inputs). It would be useful to display a count/percentage of query invalidations on a per-queery basis, as well as a diff between the old and new runs.

@Aaron1011 is this information available in self-profile currently? It should be easy to add any information from there.

Not currently - I can work on adding it.
