limit and clear cache obligations opportunistically
Keep **all** the obligations for every projection is wasteful of memory and compilation time. We only really care about those subobligations that may inform the result of the projection (i.e., may help to resolve any inference variables that appear within). Therefore, we can clear the subobligations from the cache that don't potentially affect the result of the projection. On every cache hit, we also take the opportunity to check if the type variables have been resolved *yet* and, if so, clear out the pending obligations. Fixes rust-lang#43613
