Comment (by simonmar):

 None of the arithmetic operations on `Int` check for overflow, they all
 wrap around modulo the size of the `Int` type, so it seems to me we should
 be consistent and yield 0 for this case.  Haskell 98 says that overflow is
 implementation-defined, so it's up to us what we do.

 Anyway, the place is `GHC.Real`, in the the `Integral` instance for `Int`.
 Also the various other integral types in `GHC.Int` need the same
 treatment.
