fn unique() -> fn~() { || () }

This fails because || () is inferred as fn@(). fn unique() -> fn~ { ret || (); } works as expected. Test case will be in run-pass/newlambdas-ret-infer2.

Handle trait alias definitions

Part of rust-lang#2773

This PR adds a bunch of structs and enum variants for trait aliases. Trait aliases should be handled as an independent item because they are semantically distinct from traits.

I basically started by adding `TraitAlias{Id, Loc}` to `hir_def::item_tree` and iterated adding necessary stuffs until compiler stopped complaining what's missing. Let me know if there's still anything I need to add.

I'm opening up this PR for early review and stuff. I'm planning to add tests for IDE functionalities in this PR, but not type-related support, for which I put FIXME notes.
