How can this even happen???
In the test, typeck gives an error. We bail out if the callee is tainted by errors, so we should have bailed out somewhere. Or are we missing tainting?

We don't taint a body if it's incompatible with its trait definition. But this PR is made obsolete by #133365, which does ensure we never resolve to an impl if it's incompatible with the definition of the trait.
