Rollup merge of #139502 - yaahc:still-mutable-ice, r=bjorn3
fix "still mutable" ice while metrics are enabled Resolves "still mutable" ICE discovered by `@matthiaskrgr` here: [#t-docs-rs > metrics intitiative @ 💬](https://rust-lang.zulipchat.com/#narrow/channel/356853-t-docs-rs/topic/metrics.20intitiative/near/510490790) This was caused by invoking `crate_hash` before the `definitions` struct was frozen here: https://github.com/rust-lang/rust/blob/e643f59f6da3a84f43e75dea99afaa5b041ea6bf/compiler/rustc_interface/src/passes.rs#L951 resolved by moving metrics dumping to occur after `analysis` freezes the definitions I'm guessing we didn't discover this in CI because the problem only occurs when you try to calculate the crash hash with incremental compilation enabled when it tries to freeze the definitions here: https://github.com/rust-lang/rust/blob/e643f59f6da3a84f43e75dea99afaa5b041ea6bf/compiler/rustc_middle/src/hir/map.rs#L1172 my understanding is that this causes us to freeze the definitions too early in compilation, then we subsequently try to mutate them, likely during `analysis`, and this causes the ICE. r? `@bjorn3`
