Possible specializations:

- LOAD_METHOD_CACHED
Cache the method. We only need to check that type(o) and o.__dict__ was not modified.

- LOAD_METHOD_CLASS
For classmethods. Less speedup expected.

- LOAD_METHOD_MODULE
For module methods. Uncommon (<10%).

Please see https://github.com/faster-cpython/ideas/issues/81 for more details.

Some improvements can be made (see https://github.com/python/cpython/pull/27722#issuecomment-900369714), but for the most part we're done.
