  Add an SH_GLSL_CORE_OUTPUT profile.
  
  So we could generate shaders for Apple using core GL profile.
  
  By switching to core profile, we still pass most WebGL conformance tests 1.0.2 on Linux, but not all, so apparently more work is needed.
  
  However, I think it's OK to check this CL in because this output profile will be only used behind a chromium switch.
  
  BUG=angleproject:933
  TEST=webgl conformance tests
