Move completeness check to the point where the function is defined or first called. This means we also defer deciding whether the function has a return slot until that point. Instead of storing a return slot per function, store the location of the return storage, which may or may not be used, and compute and store a separate flag saying whether to use it at the point of first use or definition. This is the final piece in supporting simple `Make` functions in classes as a replacement for constructors.
