miri no longer builds after rust-lang/rust#99553

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #99553, I observed that the tool miri has failing tests.
A follow-up PR to the repository https://github.com/rust-lang/miri is needed to fix the fallout.

cc @ChrisDenton, do you think you would have time to do the follow-up work?
If so, that would be great!

Looks like the cfg(miri) codepath doesn't build:

Yeah, sorry was just about to say. The cfg(miri) bits got out of sync with the code after edits. Fixing...
