ICE: "no entry found for key" while building stage0 tools

[yoshuawuyts]

Checked out the latest version of the compiler today to write a patch, but ran into an ICE when doing py check. I haven't changed anything recently, so not sure what's causing this.

It looks like old incremental compilation data is getting reused. I believe that this should be fixed by #86641.

In the meantime, running ./x.py clean should fix this.

Duplicate of #76720.

[jyn514]

This is not actually a duplicate. This happens in stage0, not stage1, so it's not related to sharing the version string between different dev builds. It might be the case that we're not clearing the cache when we update the beta compiler, but that will have a different fix and should be tracked separately.

(It happened to me this morning)

[jyn514]

The strange thing to me is that we shouldn't need to clear the stage0 cache - beta should just be ignoring incremental artifacts that don't match the version hash. @cjgillot @michaelwoerister do you know what could be going on here?

[jyn514]

I do think this is a purely incremental bug because rm -r build/x86_64-unknown-linux-gnu/stage0-tools/x86_64-unknown-linux-gnu/release/incremental/ fixed the issue, I didn't need to clear any .rmeta files.
