Select cpu in terms of the smallest Numa distance for a GPU device.
This will improve performance of hipMemcpy in the mode of
hipMemcpyHostToDevice or hipMemcpyDeviceToHost for small buffer.

Fix a build error in centos 6.10. When linking, ld cannot find function
clock_getres. This function is from librt (for glibc version before 2.17).

This only adds source files for ocltst and the following test modules - oclruntime, oclperf, oclgl, ocldx. There's no build files for now.

This reverts commit a3b730b595.
Reason for revert: HIP_ENABLE_LAZY_KERNEL_LOADING is needed before the runtime is initialized, so this utility cannot be used

The hipOccupancyMaxPotentialBlockSize API is meant to return the
number of threads for the highest-occupancy workgroup, and the number
of those workgroups. It was previously calculating the number of
maximum-sized workgroups that would fit on a single CU. This is
a mixture of the API we wanted (to calculate max potential block size)
and the MaxBlocksPerMultiprocessor function.
This patch fixes it up so that the internal occupancy calculation
function works for two uses: the traditional function that calculates
the maximum blocks per multiprocessor when a user passes in a fixed
block size (used for hipMaxBlocksPerMultiprocessor style functions)
and a function that calculates the size of a block that would lead
to maximum occupancy, and how many blocks of that size would be
needed to fill the whole GPU (for hipOccupancyMaxPotentialBlockSize
style functions).
This also updates the occupancy calculation function to prepare for
gfx10, which does not have SGPR-based occupancy limits.

Git may not be available, and this may not be a git checkout, as would
happen in a release tarball. Doesn't really attempt to get a nicer
version formatting if some of the git subcommands fail.

SWDEV-237377 - This fixes time calculation where the event may
be recorded on Null stream and work submitted on other streams

1. Updated FAQ with shft*sync not supported hip_faq.md
2. Corrected some of input parameter description in hcc_details/hip_runtime_api.h
3. Redirect shfl*() to shfl_*_sync() for nvcc path where CUDA > 9.0
