Promotion in bitwise operators makes better sense for unsigned integers, but
doesn't make much sense for signed integers, bitwise operators are supposed to
act on bit arrays, which signed integers are not. After deprecation the
compiler should give an error for signed integer promotions in bitwise
operators.
