groundwork for better performance. Key points: - Separate out determining which method to use from actually selecting a method (this should enable caching, as well as the pcwalton fast-reject strategy). - Merge the impl selection back into method resolution and don't rely on trait matching (this should perform better but also is needed to resolve some kind of conflicts, see e.g. `method-two-traits-distinguished-via-where-clause.rs`) - Purge a lot of out-of-date junk and coercions from method lookups.
