Turns out this wasn't bug 1634204, but bug 1624056, which is not obvious at all why, but a backout on top of m-c does fix it.

So, it turns out ahash has a feature that enables the use of a random seed generated at compile time. That feature is enabled by default, but hashbrown, which is what brings ahash in, disables its default features. But it also provides a feature to enable it, and enables that feature by default. So all the 4 crates we have in tree that pull hashbrown as a dependency (there are actually more with cranelift, but those dependencies are not enabled by default), end up enabling that compile-time random seed.

You might ask, why only now? It turns out the compile-time random seed was eliminated as dead code before bug 1624056, and that's not the case anymore, but we don't actually /need/ that.
