regression: name resolution fails to find constant?

[Mark-Simulacrum]

I'm not sure if this is our fault or something in the underlying library...

Would be good to bisect these independently to confirm it's the same root cause.

The failure in abstract-testing-0.26.1 mentioned in the OP bisects to 1b9ae9e (#150502).

...and I confirm that all those in the second post bisect to the same commit.

cc @petrochenkov @yaahc as author/reviewer of #150502. Are regressions expected from that PR? There's a note of Crater run in that PR (#150502 (comment))...
