Migrate away from the soft-deprecated functions in APInt.h (NFC)

Note that those functions on the left hand side are soft-deprecated in
favor of those on the right hand side:

  getMinSignedBits -> getSignificantBits
  getNullValue     -> getZero
  isNullValue      -> isZero
  isOneValue       -> isOne
