[issue45609] Specialize STORE_SUBSCR

[Dennis Sweeney]

New submission from Dennis Sweeney :

See the issue here for lots of data from before specializing: 
https://github.com/faster-cpython/ideas/issues/105

See https://gist.github.com/sweeneyde/91855e50feb9992b604ddda2d4f1511e for 
specialization data, pyperformance benchmarks, and microbenchmarks.

Right now the PR draft specializes list[int], dict[str], and bytearray[int], 
although I don't if the bytearray opcode should be kept. I considered 
specializing dict[object], but I figured the overhead of PyDict_SetItem isn't 
that much less than PyObject_SetItem.
