[Bug middle-end/23666] Fold does not reduce C - ~a into a + (C+1)

The problem here is my fault, slightly.  Fold is converting -(~a) in the
NEGATE_EXPR but not in the generic functions to do the negation.  I will do the
patch for this one.  (I am saying that -(~a) is more complex than a+1 which is
true).
