Damien George dd11af209d py: Add LOAD_SUPER_METHOD bytecode to allow heap-free super meth calls.
This patch allows the following code to run without allocating on the heap:

    super().foo(...)

Before this patch such a call would allocate a super object on the heap and
then load the foo method and call it right away.  The super object is only
needed to perform the lookup of the method and not needed after that.  This
patch makes an optimisation to allocate the super object on the C stack and
discard it right after use.

Damien George f9448ddc2c minimal: Add example of frozen persistent bytecode (.mpy file).
frozentest.py is frozen into the binary as frozen bytecode.  The .mpy
file is included so that there is no dependency on the cross compiler.
