Auto merge of rust-lang#73285 - Mark-Simulacrum:clippy-fail, r=RalfJung,oli-obk
Avoid prematurely recording toolstates When we're running with dry_run enabled (i.e. all builds do this initially), we're guaranteed to save of a toolstate of TestFail for tools that aren't tested. In practice, we do test tools as well, so for those tools we would initially record them as being TestPass, and then later on re-record the correct state after actually testing them. However, this would not work well if the build failed for whatever reason (e.g. panicking in bootstrap, or as was the case in rust-lang#73097, clippy failing to test successfully), we would just go on believing that things passed when they in practice did not. This commit also adjusts saving toolstate to never record clippy explicitly (otherwise, it would be recorded when building it); eventually that'll likely move to other tools as well but not yet. This is deemed simpler than checking everywhere we generically save toolstate. We also move clippy out of the "toolstate" no-fail-fast build into a separate x.py invocation; this should no longer be technically required but provides the nice state of letting us check toolstate for all tools and only then check clippy (giving full results on every build). r? @oli-obk Supercedes rust-lang#73275, also fixes rust-lang#73274
