  * UNDO: Be a little keener to inline
  
  This patch caused at least the following test failures:
     1744(normal)
     ghci028(ghci)
     unicode001(normal)
  and additionally made the stage3 build fail.  
  
  A little more validation please!
  
  I didn't find the exact cause of the failure yet, but it appears that
  the Lexer is miscompiled in some strange way.  If any of {Encoding,
  StringBuffer, or Lexer} are compiled without -O, the problem goes
  away.
