74e1737f - [mypyc] Mark magic-overlapping error handler branches as rare (#13525)

[mypyc] Mark magic-overlapping error handler branches as rare (#13525) This might slightly improve performance when using native ints, and it's consistent with how other error handler branches are treated as rare. Now the generated error handling code when calling a function that returns a native int looks something like this (the `unlikely(...)` part is new): ``` cpy_r_r0 = CPyDef_f(); cpy_r_r1 = cpy_r_r0 == -113; if (unlikely(cpy_r_r1)) goto CPyL2; ```
