* Remove 'zombie' frames. We won't need them once we are allocating fixed-size frames. * Add co_nlocalplus field to code object to avoid recomputing size of locals + frees + cells. * Move locals, cells and freevars out of frame object into separate memory buffer. * Use per-threadstate allocated memory chunks for local variables. * Move globals and builtins from frame object to per-thread stack. * Move (slow) locals frame object to per-thread stack. * Move internal frame functions to internal header.
