This adds back the handling of wrapper type vs. primitive. It leaves wrapper
vs. wrapper as returning "(Number or Comparable)" (see GROOVY-8965). I'm not
sure it properly handles number literals that will fit within the range of the
boxed type. For example "def n = flag ? (short)1234 : 0" is of type {{short}}
in Java IIRC.
