Implement rust-lang/compiler-team#578. When an ICE is encountered on nightly releases, the new rustc panic handler will also write the contents of the backtrace to disk. If any `delay_span_bug`s are encountered, their backtrace is also added to the file. The platform and rustc version will also be collected.

On nightly, dump ICE backtraces to disk Implement rust-lang/compiler-team#578. When an ICE is encountered on nightly releases, the new rustc panic handler will also write the contents of the backtrace to disk. If any `delay_span_bug`s are encountered, their backtrace is also added to the file. The platform and rustc version will also be collected. <img width="1032" alt="Screenshot 2023-03-03 at 2 13 25 PM" src="https://user-images.githubusercontent.com/1606434/222842420-8e039740-4042-4563-b31d-599677171acf.png"> The current behavior will *always* write to disk on nightly builds, regardless of whether the backtrace is printed to the terminal, unless the environment variable `RUSTC_ICE_DISK_DUMP` is set to `0`. This is a compromise and can be changed.
…er-errors Require TAITs to be mentioned in the signatures of functions that register hidden types for them r? `@lcnr` `@compiler-errors` This implements the lang team decision from [the TAIT design meeting](https://rust-lang.zulipchat.com/#narrow/stream/213817-t-lang/topic/design.20meeting.202023-05-31.20TAITs/near/362518164).
…ath, r=notriddle,fmease [rustdoc] If re-export is private, get the next item until a public one is found or expose the private item directly Fixes rust-lang#81141. If we have: ```rust use Private as Something; pub fn foo() -> Something {} ``` Then `Something` will be replaced by `Private`. r? `@notriddle`
…at-again, r=oli-obk Structurally normalize again for byte string lit pat checking We need to structurally normalize the pointee of a match scrutinee when trying to match byte string patterns -- we used[^1] to call `structurally_resolve_type`, which errors for type vars[^2], but lcnr added `try_structurally_resolve_type`[^3] in the mean time, which is the right thing to use here since it's totally opportunistic. Fixes rust-lang/trait-system-refactor-initiative#38 [^1]: rust-lang#112428 [^2]: rust-lang#112993 [^3]: rust-lang#113086
…itit-gat, r=spastorino Remove `variances_of` on RPITIT GATs, remove its one use-case It doesn't make sense to implement variances on a GAT anyways, since we don't relate GATs with variance: https://github.com/rust-lang/rust/blob/85bf07972a1041b9e25393b803d0e006bec3eaaf/compiler/rustc_middle/src/ty/relate.rs#L569-L579 r? `@spastorino`
miri: check that assignments do not self-overlap r? `@oli-obk`
