Reduce the number of `RefCell`s in `InferCtxt`.
`InferCtxt` contains six structures within `RefCell`s. Every time we create and dispose of (commit or rollback) a snapshot we have to `borrow_mut` each one of them. This commit moves the six structures under a single `RefCell`, which gives significant speed-ups by reducing the number of `borrow_mut` calls. To avoid runtime errors I had to reduce the lifetimes of dynamic borrows in a couple of places.
