Teach code completion to adjust its completion priorities based on the
type that we expect to see at a given point in the grammar, e.g., when
initializing a variable, returning a result, or calling a function. We
don't prune the candidate set at all, just adjust priorities to favor
things that should type-check, using an ultra-simplified type system.
