In core.memory, functions that do not affect the validity or contents of the
underlying memory regions should have signatures of ReturnType function(const
void*), not ReturnType function(void*). These include GC.sizeOf(), GC.addrOf(),
and GC.realloc(). There is simply no reason why these would be unsafe to call
on pointers to const/immutable objects, and as such, this should not require an
explicit cast.
