Use bitand when checking for signed integer division overflow
For `self == Self::MIN && rhs == -1`, LLVM does not realize that this is the same check made by `self / rhs`, so the code generated may have some unnecessary duplication. For `(self == Self::MIN) & (rhs == -1)`, LLVM realizes it is the same check.
