P4 to Git Change 1161661 by skudchad@skudchad_test_win_opencl2 on 2015/06/15 17:50:19

EPR #420701 - WDDM 2.0
	- Indicate lite initialization via a new parameter initLite. This is needed as OCL\OGL can query devices first and lot of  setup in IOL may not be really needed. On Win10, we create paging\fences for sync which dont get destroyed by the OS unless process is killed. This may prevent slave GPU powerdown in PX cases.
	- Disable WriteFence for OpenCL for now.
