- Make temporaries in if-let guards be the same variable in MIR when
the guard is duplicated due to or-patterns.
- Change the "destruction scope" for match arms to be the arm scope rather
than the arm body scope.
- Add tests.
Add better ICE messages for some undescriptive panics

re: #118955
I took a look at some others but either was not able to figure out what they did, or it was unclear what they should say instead. For example in the query system whether each time a poisoned value is matched upon if they should all just call `FatalError.raise()`
[AIX] Fix XCOFF metadata
#118344 accidentally changed the way to get metadata from XCOFF file and broken our internal CI.

coverage: Skip instrumenting a function if no spans were extracted from MIR
The immediate symptoms of #118643 were fixed by #118666, but some users reported that their builds now encounter another coverage-related ICE:
```
error: internal compiler error: compiler/rustc_codegen_llvm/src/coverageinfo/mapgen.rs:98:17: A used function should have had coverage mapping data but did not: (...)
```
I was able to reproduce at least one cause of this error: if no relevant spans could be extracted from a function, but the function contains `CoverageKind::SpanMarker` statements, then codegen still thinks the function is instrumented and complains about the fact that it has no coverage spans.
This PR prevents that from happening in two ways:
- If we didn't extract any relevant spans from MIR, skip instrumenting the entire function and don't create a `FunctionCoverateInfo` for it.
- If coverage codegen sees a `CoverageKind::SpanMarker` statement, skip it early and avoid creating `func_coverage`.

resolve: Replace visibility table in resolver outputs with query feeding
Also feed missing visibilities for import stems and trait impl items, which were previously evaluated lazily.
I suspect that in general this approach should work for queries that are 1) executed for most keys and 2) have results that are cheap to hash (do not have spans, in particular).
Visibility query matches that description.
adds a column number to `dbg!()`
this would be very nice to have for a few reasons:
1. the rfc, when deciding not to add column numbers to macro, failed to acknowledge any potential ambiguous cases -- such as the one provided in #114910 -- which do exist
2. would be able to consistently and easily jump directly to the `dbg!()` regardless of the sutation
3. takes up, at a maximum, 3 characters of _horizontal_ screen space
fixes#114910
Remove unnecessary constness from ProjectionCandidate
Constness in an item bound will be represented by an effect param, so no need to record constness here.

fix: Overlapping spans in delimited meta-vars
Closes#118786
Delimited meta-vars inside of MBE's spans were set to have the same opening and closing position resulting in an ICE when debug assertions were enabled and an error was present in the templated code.
This ensures that the spans do not overlap, whilst still having the spans point at the usage of the meta-var inside the macro definition.
It includes a regression test.

More expressions correctly are marked to end with curly braces
Fixes#118859, and replaces the mentioned match statement with an exhaustive list, so that this code doesn't get overlooked in the future
skip rpit constraint checker if borrowck return type error
Fixes#117794Fixes#117886Fixes#119025
Prior to change #117418, the value of `concrete_opaque_types` for `mir_borrock(T:🅰️:opaque)` was `None`. However, due to modifications in `body.local_decls`, the return value had been changed.
The changed of `body.local_decls` has let to the addition of `ty:Error` to `infcx.opaque_type_storage.opaque_types` during `TypeChecker::equate_inputs_and_outputs`. This is due to it utilizing the output of a function signature that was appended during `construct_error`(which previously only appended a `ty::Error`) and then execute `TypeChecker::Related_types`.
Therefore, in this PR, I've implemented a condition to bypass the rpit check when an error is encountered.
