We only want to compute the reason if stats are enabled. Optimizing compilers should optimize this away for us (gcc and clang do), but it's better to be safe than sorry.

lgtm, because it just move back to previous version.
Sharing my one of idea is (I didn't take a look deeply if it is possible or not):
- providing two version of xxxx_op_fail_kind function based
Py_STATSand ifPy_STATSis disabled, just return dummy value like -1, - Inside
unspecialize(_Py_CODEUNIT *instr, int reason), if the reason is just dummy value than calculate nothing.
