I have an open PR to the Miri repo adding tests for this behavior rust-lang/miri#3688, but that unfortunately hits the ICE path here. The changes seem reasonably low risk that it might be okay to merge separately from the tests, and I tested the result locally against an older version of rust-lang/miri#3688.

Technically you should be able to test this from const eval now, right?

Yeah I think this unblocks the only exposed codepath, the remaining changes in miri are just intrinsics that we don't have library functions for. Miri just has a good structure for casting tests so it seems easiest to make use of what is there
