It is no longer necessary as __rust_start_panic switched to the Rust abi.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

Miri uses miri_start_panic as unwind entrypoint, which is called by panic_unwind's __rust_start_panic, so no miri changes needed afaict.

For reference, my previous comment was "I think this will require changes to Miri". I deleted it shortly after posting it, as I realized it was incorrect :)

This looks like a nice improvement. Maybe squish the commits though?
