Research direction

Start by locating the CALL_FUNCTION_EX entry point and the existing call-frame inlining optimization, then compare how that optimization is applied to other call paths. Done means the optimization also covers calls using *args and **kwargs, with the relevant CPython checks passing.

Description

3.13 interpreter-core performance type-feature

We should apply the call frame inling optimisation to CALL_FUNCTION_EX. Many instances in real world code use *args or **kwargs and they would benefit from this optimisation.
