Whether the definition of this global may be replaced at link time.

The intrinsic ID for this subclass (which must be a Function).

This member is defined by this class, but not used for anything. Subclasses can use it to store their intrinsic ID, if they have one.

This is stored here to save space in Function on 64-bit hosts.
