  Add new shader inspection APIs.
  
  Each new entry point corresponds to one of the variable types:
  varyings, attributes, uniforms, output variables, and interface
  blocks. They return a pointer to the vector with all of the
  parsed variables, which then the app can copy to its own memory.
  
  Currently we do not support the staticUse field in the HLSL
  translator.
