In which we start tracking polonius in -Z self-profile

[lqd]

This PR adds 2 -Z self-profile activities:

• "polonius_fact_generation" to track the different places where we convert MIR/NLL data to polonius facts
• "polonius_analysis" to track the time polonius itself takes to do its job: some move/init analysis (and more to come soon), liveness, borrow checking.

cc @AlbinS for the commits slightly refactoring the liveness fact generation (to make it easier to use the measureme profiler), what do you think ? I know you've wanted to refactor liveness fact generation in general (even though we'll do broader changes when that happens). I also hope I haven't missed relations.

cc @rust-lang/wg-polonius in general: like most of -Z self-profile + summarize, the profiling is done per-session/per-crate (?) and thus here we won't differentiate between functions/DefIds either, but (depending on the tool) commonly aggregate the different polonius durations. While we know it'll be needed in the future, and should be relatively easy to track with the profiler, would the profiling information in this PR be worthwhile on its own until then ? (Or would you rather we try to do that now ?). It would seem useful to eventually have both: one view would be high-level (and helpful to compare and track performance over time), and the other fine-grained, knowing exactly what time each def_id took, to spot specific problems/outliers (either in rustc/polonius or in user code). Hence, this PR as a first step towards that.

Here are a couple examples (taken on stage 1) post-processed with summarize:

r? @wesleywiser for the profiler usage

[wesleywiser]

Looks great to me! Unless @AlbinS or @rust-lang/wg-polonius has any feedback for your other changes, feel free to r=me.

[wesleywiser]

like most of -Z self-profile + summarize, the profiling is done per-session/per-crate (?) and thus here we won't differentiate between functions/DefIds either, but (depending on the tool) commonly aggregate the different polonius durations. While we know it'll be needed in the future, and should be relatively easy to track with the profiler, would the profiling information in this PR be worthwhile on its own until then ? (Or would you rather we try to do that now ?)

I don't want to promise anything but @michaelwoerister has been making a lot of progress in capturing query keys in the self-profiler. Unless this is blocking your work, I think we should wait for the self-profiler to handle this natively. Hopefully that will be very soon!

[amandasystems]

The refactoring I had in mind was much larger, encompassing virtually all the fact generation for Polonius, but this looks great and I have no objections!

[amandasystems]

Also, I look forward to seeing the refactored version run faster than this when I profile it ;)
