I'm so dumb -- this doesn't actually even test that this PR does anything :(
The error comes from i32: Trait WF obligation from <i32 as Trait>::Assoc.

this test also doesn't enable -Znext-solver

…=lcnr Walk into alias-eq nested goals even if normalization fails Somewhat broken due to the fact that we don't handle aliases well, nor do we handle ambiguities well. Still want to put up this incremental piece, since it improves type errors for projections whose trait refs are not satisfied. r? lcnr
