  Only initialize globals if initialization flag is set
  
  This avoids the possibility of initializing globals twice in Chromium.
  Now we also never initialize variables redundantly in case we're
  writing HLSL output. This was already the intent of the code before,
  but a mistake had slipped in and the code didn't actually check the
  output type properly.
  
  This also simplifies DeferGlobalInitializers by running it after
  SeparateDeclarations.
