bpo-46409: Make generators in bytecode (GH-30633)

Browse source 
* Add RETURN_GENERATOR and JUMP_NO_INTERRUPT opcodes.

* Trim frame and generator by word each.

* Minor refactor of frame.c

* Update test.test_sys to account for smaller frames.

* Treat generator functions as normal functions when evaluating and specializing.
