This describes the types that can be contained in a generator. It will be a type variable initially and unified in the last stages of typeck of a body. It contains a tuple of all the types that could end up on a generator frame. The state transformation MIR pass may only produce layouts which mention types in this tuple. Upvars are not counted here.

Return the "generator signature", which consists of its yield and return types.

NB. Some bits of the code prefers to see this wrapped in a binder, but it never contains bound regions. Probably this function should be removed.

This returns the types of the MIR locals which had to be stored across suspension points. It is calculated in rustc_mir::transform::generator::StateTransform. All the types here must be in the tuple in GeneratorInterior.
