Remove `verbose_generic_activity_with_arg`
This removes `verbose_generic_activity_with_arg` and changes users to `generic_activity_with_arg`. This keeps the output of `-Z time` readable while these repeated events are still available with the self profiling mechanism.
fix: return early when has tainted in mir-lint
Fixes#115203
`a[..]` is of indeterminate size, it had been reported error during borrow check, therefore we skip the mir lint process.
coverage: Simplify the `coverageinfo` query
The `coverageinfo` query walks through a `mir::Body`'s statements to find the total number of coverage counter IDs and coverage expression IDs that have been used, as this information is needed by coverage codegen.
This PR makes 3 nice simplifications to that query:
- Extract a common iterator over coverage statements, shared by both coverage-related queries
- Simplify the query's visitor from two passes to just one pass
- Explicitly track the highest seen IDs in the visitor, and only convert to a count right at the end
I also updated some related comments. Some had been invalidated by these changes, while others had already been invalidated by previous coverage changes.
Don't report any errors in `lower_intrinsics`.
Intrinsics should have been type checked earlier.
This is part of moving all mir-opt diagnostics early enough so that they are reliably emitted even in check builds: https://github.com/rust-lang/rust/issues/49292#issuecomment-1692212095
Both of the coverage queries can now use this one helper function to iterate
over all of the `mir::Coverage` payloads in the statements of a `mir::Body`.
Represent MIR composite debuginfo as projections instead of aggregates
Composite debuginfo for MIR is currently represented as
```
debug name => Type { projection1 => place1, projection2 => place2 };
```
ie. a single `VarDebugInfo` object with that name, and its value a `VarDebugInfoContents::Composite`.
This PR proposes to reverse the representation to be
```
debug name.projection1 => place1;
debug name.projection2 => place2;
```
ie. multiple `VarDebugInfo` objects with each their projection.
This simplifies the handling of composite debuginfo by the compiler by avoiding weird nesting.
Based on https://github.com/rust-lang/rust/pull/115139
Use relative positions inside a SourceFile.
This allows to remove the normalization of start positions for hashing, and simplify allocation of global address space.

Fix inlining with -Zalways-encode-mir
Only inline functions that are considered eligible for inlining
by the reachability pass.
This constraint was previously indirectly enforced by only exporting MIR
of eligible functions, but that approach doesn't work with
-Zalways-encode-mir enabled.
