@nikomatsakis Thanks. This PR isn't compiling yet, AFAIR, due to some unconstrained variables in rustc but the general direction is mostly set. I will rebase soon.

PR rust-lang#17603 introduced bottom type fallback but did it a bit too
eagerly. This patch makes the fallback lazy so that `typeck` can run
its cause and detect as many type errors as possible with regard to
diverging types.
