Move type checks from switch cases to beginning of `_Py_Specialize_BinaryOp`

Feature or enhancement

Proposal:

_Py_Specialize_BinaryOp: https://github.com/python/cpython/blob/aeb9b65aa26444529e4adc7d6e5b0d3dd9889ec2/Python/specialize.c#L2380-L2443
uses

if (!Py_IS_TYPE(lhs, Py_TYPE(rhs))) { 
    break; 
} 

check inside every switch case which is redundant. Placing this check before switch results in same performance but less generated code. Compiler with -O3 option seems to not recognize it. Attaching generated machine code (clang, apple silicon) for old and new versions
new.txt
old.txt

Feel free to close this if not worth it.

Has this already been discussed elsewhere?
