  	-------------------------------
  	Improve orphan-module resolution
  	-------------------------------

  Consider the following rule (and there are lots of these in
  the Prelude):

  	fromIntegral T = fromIntegral_T

  where T is defined in the module being compiled.

  is an orphan.  Of course it isn't, an declaring it an orphan would
  make the whole module an orphan module, which is bad.

  This commit arranges to determine orphan rules, and the orphan-hood
  of a module, much later than before.  (Before mi_orphan was set by
  the renamer, now it is set by MkIface.)
