Add regression test for #127424

Fixes: https://github.com/rust-lang/rust/issues/127424

This ICE no longer reproduces, so it appears to have already been fixed.
This PR adds a regression test to ensure the issue doesn’t come back in the future.

Please let me know if there's anything I should improve or revise!

d00d4dfe0d Refactor dyn-compatibility error and suggestions 
This CL makes a number of small changes to dyn compatibility errors:
- "object safety" has been renamed to "dyn-compatibility" throughout
- "Convert to enum" suggestions are no longer generated when there
  exists a type-generic impl of the trait or an impl for `dyn OtherTrait`
- Several error messages are reorganized for user readability

Additionally, the dyn compatibility error creation code has been
split out into functions.

5b54286640 Remove detail from label/note that is already available in other note 
Remove the "which is required by `{root_obligation}`" post-script in
"the trait `X` is not implemented for `Y`" explanation in E0277. This
information is already conveyed in the notes explaining requirements,
making it redundant while making the text (particularly in labels)
harder to read.
