  this is a warning hack. The idea is to use this everywhere that we
  get the "discarding const" warning from gcc. That doesn't actually
  fix the problem of course, but it means that when we do get to
  cleaning them up we can do it by searching the code for
  discard_const.

  It also means that other error types aren't as swamped by the noise
  of hundreds of const warnings, so we are more likely to notice when
  we get new errors.

  Please only add more uses of this macro when you find it
  _really_ hard to fix const warnings. Our aim is to eventually use
  this function in only a very few places.

  Also, please call this via the discard_const_p() macro interface, as that
  makes the return type safe.
