Handle and recover `match expr { pat >= { arm } }`.
When encountering a type error involving a `Self` literal, point at the self type of the enclosing `impl`. CC rust-lang#76086.
When encountering a type error caused by the use of `Self`, suggest
using the actual type name instead.

Fix rust-lang#76086.
Building rustc with `--rust-profile-use` is currently dumping a lot of warnings of "no profile data available for function" from `rustc_smir` and `stable_mir`. These simply aren't exercised by the current profile- gathering steps, but that's to be expected for new or experimental functionality. I think for most people, these warnings will be just noise, so it makes sense to only have them in verbose builds.

Better handle type errors involving `Self` literals
When encountering a type error involving a `Self` literal, point at the self type of the enclosing `impl` and suggest using the actual type name instead.

bootstrap: only show PGO warnings when verbose Building rustc with `--rust-profile-use` is currently dumping a lot of warnings of "no profile data available for function" from `rustc_smir` and `stable_mir`.
