Split testNumber/testDivisible into Bounded and unbounded variants and skip just that one pair, gated by `(minBound :: a) < 0` so unsigned types lose no coverage. * The `mulIntMayOflo#` test compared raw Int# bit-for-bit, but the primop is only specified to return 0/non-zero -- the exact non-zero indicator legitimately differs between backends and inlining choices. Add a dedicated `testPrimopMayOflo` helper that only compares zero / non-zero. Also fix the long-standing typo "Dividible" -> "Divisible" in identifiers.
