…sleywiser Add support for artifact size profiling This adds support for profiling artifact file sizes (incremental compilation artifacts and query cache to begin with). Eventually we want to track this in perf.rlo so we can ensure that file sizes do not change dramatically on each pull request. This relies on support in measureme: rust-lang/measureme#169. Once that lands we can update this PR to not point to a git dependency. This was worked on together with `@michaelwoerister.` r? `@wesleywiser`

This adds support for a new kind of
{Raw,Lightweight,}Event: integer events in order to support artifact size measurements. In the meantime it also refactors the other events to be more clearly about timestamps. Some code assumes timestamps, and this change makes it more clear where those assumptions are.In order to test this, using a compiler built with rust-lang/rust#87404 is necessary.
Here's what summarize produces now for artifact sizes:
