LGTM, with my rudimentary understanding of the internal machinery.

…ngh-104203) In preparation for a per-interpreter GIL, we add PyInterpreterState.ceval.gil, set it to the shared GIL for each interpreter, and use that rather than using _PyRuntime.ceval.gil directly. Note that _PyRuntime.ceval.gil is still the actual GIL.

PyInterpreterState.ceval.gil, set it to the shared GIL for each interpreter, and use that rather than using_PyRuntime.ceval.gildirectly. Note that_PyRuntime.ceval.gilis still the actual GIL.There is a <1% performance penalty.
