  Remove invariant declaration in vertex shader for translation from ESSL 3.00 to GLSL <= 4.1
  
  This is a follow-up patch of
  https://chromium-review.googlesource.com/408569. This CL removes
  invariant declaration in ESSL 3.00 vertex shader, such like:
  "
  out vec4 foo;
  invariant foo;
  "
  
  This CL also adds the workarounds in libANGLE.
