Niko Matsakis 168ac5290e Move comparing of impl methods against trait from collect to check.
This code fits better in check because it is checking that the impl
matches the interface. This allows us to avoid the awkward constructions
that lazilly collect traits and so forth. It also permits us to make
use of the results of variance inference.
