Topic: profiling incremental re-use

@mw what is the easiest way for me to get some idea of how much re-use a given crate is getting? I'd like to explore why the https://github.com/lark-exploration/lark crates seem to take so much more time to recompile than I would expect. They are using salsa, so they have the property that they push a lot of the code into the final crate where the full "database type" is known, so my theory is that something about our partitioning or CGU scheme winds up forcing us to rebuild a lot more than you might expect.

-Zincremental-info should give you statistics on what's re-used and what isn't.
