Description: For better specialization of LOAD_METHOD. Cons: All LOAD_ATTR slows down slightly due to additional SET_TOP and STACK_GROW. Base LOAD_ATTR (unspecialized) gets one more branch. All LOAD_ATTR cache becomes much bigger. We need to mitigate this with faster-cpython/ideas#396 EXTENDED_ARGS for LOAD_ATTR/METHOD in large modules Pros: Theoretically, what was previously LOAD_METHOD should now have better specialization because we can just treat it like specializing a normal attribute. We save three opcodes. We de-duplicate lots of code shared between LOAD_METHOD and LOAD_ATTR. Fixes #93429.
