[compiler-errors]

The title of this issue doesn't really explain why it's an ICE. Specifically, there's no explanation for why we're encountering an inference variable in the type of a constant inside of a param-env, which is why this ICE occurs.

[compiler-errors]

This is not the right solution, and causes us to totally ignore canonicalization for infer vars when the infcx is not provided. I'm pretty surprised that this even passes at all!
