P4 to Git Change 2049201 by skudchad@skudchad_test2_win_opencl on 2019/12/20 11:44:13

SWDEV-216708 - [hipclang-vdi-rocm][FBA-77]hipGetDeviceCount() query should not trigger any queue creation.
	- KFD queues get created when we call hsa_executable_load_agent_code_object when creating a blitProgram at init. Delay blit creation until when needed
	- Queue also gets created when we init a xferQueue. Delay that too until when needed.

	If we want to have a lite init, there are multiple changes needed in both OpenCL and HIP. Thats rather a feature to work on later.
