+ Fix the error in cmake: clang 8.0.0 supports CUDA 10.0, not 10.1; only trunk clang 9.0.0 supports CUDA 10.1.
+ Update Readme:
  1. clang's bug 36384 is gone, so latest stable release for Linux is clang 8.0.0, which supports CUDA up to 10.0;
  2. update dependencies, testing and building notes.

SWDEV-144570 - Fix pointer attribute query.

	- For memory not registered with runtime, return
	  `hipErrorInvalidValue`. That's the behavior expected to check whether
	  a host buffer is pinned.
	- Return `hipErrorInvalidDevice` in case a registered memory object
	  cannot find its matching device.

SWDEV-183848 - Update OpenCL perfcounter blocks to match the block lists used by GPUPerfAPI (which is in turn used by RCP and CodeXL)

	- The PAL block index for the PA_SC block was incorrect in all hw generations (in PAL, GpuBlock::SC has ordinal 4, not 3)
	- In GFX9, the MC and SRBM blocks are not supported
	- In GFX10, the following changes are made:
	  -- There are 8 CB instances per SE
	  -- There are 8 DB instances per SE
	  -- There are 2 PA_SU instances per SE
