Please take a look, with special focus on:

- Benedikt: Code stub generation changes
Description:
Create a internal native context used only for TF- generated code stubs
Until now, TF-generated code stubs piggy-backed off of the builtin
context. Since generation of code stubs is lazy, stubs generated at
different times in different native contexts would contain embedded
pointers different builtin contexts, leading to cross-context references
and memory leaks.
After this CL, all TF-generated code stubs are generated inside a
internal thinned-out, native context that specifically liveas for the
purpose of hosting generated code stubs.
