  * Retain inline-pragma information on unfoldings in interface files
  
  	WARNING: this patch changes interface-file formats slightly
  	 	 you will need to recompile your libraries
  
  Duncan Coutts wanted to export a function that has a NOINLNE pragma
  in a local let-defintion.  This works fine within a module, but was 
  not surviving across the interface-file serialisation.

  Regardless of whether or not he's doing something sensible, it seems
  reasonable to try to retain local-binder IdInfo across interface files.
  This initial patch just retains inline-pragma info, on the grounds that
  other IdInfo can be re-inferred at the inline site.
  
  Interface files get a tiny bit bigger, but it seesm slight.
