... as a pair of Code and CodeDataContainer.
In order to stop creating and using trampoline Code objects for
builtins we need a different way to represent an "embedded builtin"
code lookup result of builtin trampoline Code objects.
We can't switch to CodeT for this purpose because GC still needs to
be able to locate not yet evacuated Code objects in order to update
old code pointers on the stack once Code objects are moved.
