I tried to benchmark b''.decode(encoding='ascii'): CALL_METHOD is not used for this call, but CALL_FUNCTION_KW :-/ So the call is not affected by your patch.

I also ran a quick benchmark on loadmethod-methoddescr.patch:

b''.decode(): 71.1 ns +- 0.5 ns -> 65.4 ns +- 0.2 ns: 1.09x faster (-8%)
b''.decode('utf8'): 92.8 ns +- 0.4 ns -> 85.5 ns +- 0.3 ns: 1.09x faster (-8%)

I confirm the speedup.
