  Re-land "D3D: Generate more shader debug info by default."
  
  Re-land with fix for shader size query.
  
  The debug info can be very useful to WebGL developers. Instead of
  hiding the feature behind an unsupported and broken flag, always
  enable it so that WebGL devs can access the useful translated info.
  
  Change the debug info policy to build the full info (including
  generated assembly) in Debug, and all info excepth the assembly
  in Release.
