Currently, `Handler::fatal` returns `FatalError`. But `Session::fatal` returns `!`, because it calls `Handler::fatal` and then calls `raise` on the result. This inconsistency is unfortunate. This commit changes `Handler::fatal` to do the `raise` itself, changing its return type to `!`. This is safe because there are only two calls to `Handler::fatal`, one in `rustc_session` and one in `rustc_codegen_cranelift`, and they both call `raise` on the result. `HandlerInner::fatal` still returns `FatalError`, so I renamed it `fatal_no_raise` to emphasise the return type difference.
They each have a single call site.
They each have a single call site. Note: the `make_diagnostic_builder` calls in `lib.rs` will be replaced in a subsequent commit.
`sess` is a terribly misleading name for a `Handler`! This confused me for a bit.
That's what is mostly used. This commit changes a few `EM` and `E` and `T` type variables to `G`.
`Diagnostic::new` can be used instead.
These impls are all needed for just a single `IntoDiagnostic` type, not a family of them. Note that `ErrorGuaranteed` is the default type parameter for `IntoDiagnostic`.
By making it generic, instead of only for `EmissionGuarantee = ()`, we can use it everywhere.
`Handler` is a wrapper around `HanderInner`. Some functions on on `Handler` just forward to the samed-named functions on `HandlerInner`. This commit removes as many of those as possible, implementing functions on `Handler` where possible, to avoid the boilerplate required for forwarding. The commit is moderately large but it's very mechanical.
This is weird: `HandlerInner::emit` calls `HandlerInner::emit_diagnostic`, but only after doing a `treat-err-as-bug` check. Which is fine, *except* that there are multiple others paths for an `Error` or `Fatal` diagnostic to be passed to `HandlerInner::emit_diagnostic` without going through `HandlerInner::emit`, e.g. `Handler::span_err` call `Handler::emit_diag_at_span`, which calls `emit_diagnostic`. So that suggests that the coverage for `treat-err-as-bug` is incomplete. This commit removes `HandlerInner::emit` and moves the `treat-err-as-bug` check to `HandlerInner::emit_diagnostic`, so it cannot by bypassed.
This makes `Handler::fatal` more like `Handler::{err,warn,bug,note}`.
…pressions_from_macros` This already wasn't passed in bootstrap.py and the lint itself already warns-by-default for 2 years now and has already been added to the future-incompat group in Rust 1.68. See rust-lang#79813 for the tracking issue.

…compiler-errors Add support for making lib features internal We have the notion of an "internal" lang feature: a feature that is never intended to be stabilized, and using which can cause ICEs and other issues without that being considered a bug. This extends that idea to lib features as well. It is an alternative to rust-lang#115623: instead of using an attribute to declare lib features internal, we simply do this based on the name. Everything ending in `_internals` or `_internal` is considered internal. Then we rename `core_intrinsics` to `core_intrinsics_internal`, which fixes rust-lang#115597.
…tebank Pretty print `Fn<(..., ...)>` trait refs with parentheses (almost) always It's almost always better, at least in diagnostics, to print `Fn(i32, u32)` instead of `Fn<(i32, u32)>`. Related to but doesn't fix rust-lang#118225. That needs a separate fix.
…or-diagnostic, r=lcnr Add `deeply_normalize_for_diagnostics`, use it in coherence r? lcnr Normalize trait refs used for coherence error reporting with `-Ztrait-solver=next-coherence`. Two things: 1. I said before that we can't add this to `TyErrCtxt` because we compute `OverlapResult`s even if there are no diagnostics being emitted, e.g. for a reservation impl. 2. I didn't want to add this to an `InferCtxtExt` trait because I felt it was unnecessary. I don't particularly care about the API though.
