  Allow 'defined' in define in non-WebGL.
  
  This is needed to pass dEQP conformance. Several of the harder dEQP
  tests around this behaviour are excluded from the mustpass list. This
  is presumably because the behaviours weren't implemented portably.
  Nevertheless we need to support conformant behaviour for GLES 2.0
  Contexts for the most simple uses.
  
  This also leaves the error behaviour intact for WebGL specs.
