Some of these are allocated upon initialization of the intrinsics, and some lazily, but in neither case the getters actually return a nullptr. This saves us a whole bunch of pointer dereferences (as NonnullGCPtr has an `operator T&()`), and also has the interesting side effect of forcing us to explicitly use the FunctionObject& overload of call(), as passing a NonnullGCPtr is ambigous - it could implicitly be turned into a Value _or_ a FunctionObject& (so we have to dereference manually).
