`miri` no longer builds after rust-lang/rust#62335

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #62335, 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 @Mark-Simulacrum, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @Mark-Simulacrum, the PR reviewer, and @rust-lang/compiler -- nominating for prioritization.

Looks like a bunch of tests are affected the same way:

[RalfJung]

Cc @christianpoveda this is likely caused by your change, somehow.

[RalfJung]

Likely caused by a missing force_ptr in function pointer validation. Should be fixed by #62245.

[pvdrz]

I merged @RalfJung's branches with my branches in both the rust and miri repos and all the tests passed :D
