Trying Out MESA_NO_ERROR / KHR_no_error Support On Mesa 17.2-dev

Merged last month into Mesa Git and improved since then with follow-up commits has been KHR_no_error support for reducing the overhead of the OpenGL drivers by disabling certain error handling for OpenGL games/applications. This in turn can free up some CPU utilization and possibly lead to power-savings too.
