When a coroutine has too many parameters, `check_match` fails and `construct_error` builds a MIR body with only the coroutine's computed args (env + resume type). The user-provided signature, however, still reflects all the parameters the user wrote. `check_signature_annotation` then tries to `zip_eq` these two mismatched iterators, causing a panic. Checking `tainted_by_errors` and bailing early avoids this, since `construct_error` bodies cannot meaningfully be compared against user annotations.
The span location of the last segment in the desugared path is inherited from the star symbol's span
…on body Instead of the last segment of the delegation path. `self` is something that introduced by the whole delegation item, not some specific part of it, and the last segment may need to have a different context for path resolution purposes.
delegation: Track more precise spans for glob delegations The last commit also fixes a macro hygiene issue with `self` in delegations found in rust-lang#154002.
coroutines: Skip the closure signature annotation check for tainted bodies

Example currently ICEing:
```rust
fn main() {
|(1, 42), ()| yield;
}
```
Closes rust-lang#139570.
