Regarding schedules for Intel graphics

@Laurawly @tqchen
I have a question based on the issue discussed here https://github.com/dmlc/tvm/issues/1420
For Intel integrated GPU cards which does not belong to “Intel® Processor Graphics Gen9” category
(Ex .In my case Intel HD4600 integrated GPU (Haswell arch) ) , which Schedule i can use ?
As explained in the ‘issue-1420’ the schedule for intel_graphics is not suitable for the above GPU model as the accuracy is wrong .

@hrgraj The default opencl schedule (which links to cuda scheduler) will be the one better to used for now.
