Currently, the code that updates `bestguess` using `ReturnNode` information includes hardcodes that relate to `Conditional` and `LimitedAccuracy`. These behaviors are actually lattice-dependent and therefore should be overloadable by `AbstractInterpreter`. Additionally, particularly in Diffractor, a clever strategy is required to update return types in a way that it takes into account information from both the original method and its rule method (xref: JuliaDiff/Diffractor.jl#202). This also requires such an overload to exist. In response to these needs, this commit introduces an implementation of a hook named `update_bestguess!`.
