Patches listed below implement the GL_ARB_sample_shading extension on Intel hardware >= gen6. I verified the implementation with a number of piglit tests, currently under review on piglit mailing list. Observed no piglit, gles3 CTS regressions with these patches on SNB & IVB. These patches can also be found at my github branch: https://github.com/aphogat/mesa.git branch: sample-shading-5
