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 faster-cpython/ideas#81 for more details.

Some improvements can be made (see #27722 (comment)), but for the most part we're done.
