Convert predicates into Predicate in the Obligation constructor

instead of having almost all callers do that.

This reduces a bit of boilerplate, and also paves the way for my work towards https://github.com/rust-lang/compiler-team/issues/531 (as it makes it easier to accept both goals and clauses where right now it only accepts predicates).
