track individual proc-macro expansions in the self-profiler As described in [this zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Macro.20expansion.20performance.20on.20complex.20macros/near/275063190), users don't currently have a lot of information to diagnose macro expansion performance issues. That comment suggests using the macro names to add further timing information. This PR starts to do this for proc-macros which have the same issue, and performance problems happening in the wild in [this other zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/247081-t-compiler.2Fperformance/topic/Identifying.20proc-macro.20slowdowns) could be helped by such information. It uses the available proc-macro name to track their individual expansions with self-profiling events. r? `@Aaron1011` who mentioned this idea originally |
