I think https://github.com/apple/llvm-project/commit/4a51a102a0cb8746746f6819678dbced3e11d1c8 is the root cause. After this patch, CoroSplit pass leaves musttail call in the transforming function. The pass also runs IR verifier for the transforming function, and the left musttail call triggers verifier assertion.

The root problem here is that CoroSplit creates a musttail even though the target doesn't support it, I think. I'm writing a patch to fix it.
