n.b. This only handles supertrait method calls on |
Add a new method_super origin for supertrait methods. Also make coherence create a table that maps pairs of trait IDs and self types to impl IDs, so that it's possible to check a supertrait method knowing only its index in its trait's methods (without knowing all supertraits for a given trait). As per rust-lang#3979

r+ from a style and direction perspective (and it looks great); unfortunately it also looks Serious enough that I'm not real comfortable pretending to be able to judge semantic correctness. Maybe get someone who knows the numerous related invariants to double-check? |

@nikomatsakis - Can you double-check? |

@catamorphism ok will take a look today |
