Generalizes catch blocks to include any PartialFunction[Throwable, T].
Existing catch blocks will compile exactly as before. Anything else
(which mean: the token after CATCH is not a left brace, or it is a left
brace not immediately followed by CASE) is desugared as follows:

  try body catch expr
  // becomes
  try body
  catch { case x =>
    val catchFn = expr
    if (catchFn isDefinedAt x) catchFn(x)
    else throw x
  }
