* Enable specialization of CALL_KW * Fix bug pushing frame in _PY_FRAME_KW `_PY_FRAME_KW` pushes a pointer to the new frame onto the stack for consumption by the next uop. When pushing the frame fails, we do not want to push the result, `NULL`, to the stack because it is not a valid stackref. This works in the default build because `PyStackRef_NULL` and `NULL` are the same value, so the `PyStackRef_XCLOSE()` in the error handler ignores it. In the free-threaded build the values are not the same; `PyStackRef_XCLOSE()` will attempt to decref a null pointer.
