  Translator: Remove the "variables" option
  
  Variable collection is invariably enabled by the front-end as well as
  other major users of ANGLE such as Firefox.  All translator backends
  except GLSL force-enable variable collection either way.
  
  This change removes this compile option and enables variable collection
  unconditionally.
  
  The flag itself remains in ShCompileOptions until references to it are
  removed from Chromium.
