Port merged design from explore/merged-on-main 
- _GUARD_NOS/TOS_INT use PyLong_CheckExact (accepts all exact ints)
- _BINARY_OP_{ADD,SUBTRACT,MULTIPLY}_INT removed BothAreCompact assert
- Pure ops have ERROR_IF for int64 overflow
- _PyCompactLong_{Add,Subtract,Multiply} branch internally on compactness
- Removed all remaining _WIDE dead code
- Regenerated case files
