(incremental?) ICE during rustc development

[CAD97]

Minimizing from rustc is pretty impossible, and my attempts so far to deliberately provoke this didn't work. I initially got this error from the bootstrap/beta compiler while compiling rustdoc. This time it randomly happened again, but this time from my dev rustc on stage1 core.

It doesn't occur again after an x.py clean, thus the though that it is incremental metadata related.

ICEs in stage 1 are likely #76720. If you see ICEs in stage 0, those are more likely to be real bugs.

Closing this since it's likely a dupe.
