The extension is optional, partial support exists in atomic.cl, so can
be added back if that becomes a requirement.

If a sub-device cannot be further sub-divided, the v1.2 spec allows
the implementation to return CL_DEVICE_PARTITION_FAILED, or CL_INVALID_VALUE
depending on one's interpretation.
The Khronos v1.2 device_partition test fails in either case (which appears
to be a bug).
The Khronos v2.0 device_partition test was modified to accept the
return value of CL_DEVICE_PARTITION_FAILED, which is a logical fix.
This patch allows a similarly modified (fixed) Khronos v1.2 test to
pass the test subroutine code which recursively subdivides devices.

Used by clients to determine how a (sub)device was partitioned by
clCreateSubDevices()

Devices were previously being created during enumeration even when client
was not asking for the devices.
This is fixed.

This is a WIP patch beginning the addition of the v1.2 device fission
feature.

This patch allows Khronos conformance test 'computeinfo' to pass.
Device fission is not implemented yet, so the values here report
that only one device is present, and no sub-devices can be created.

Also, updated CL_DEVICE_LOCAL_MEM_SIZE and Buffer::Buffer() constructor
so that Khrnos basic "prefetch" test can pass.
Previously, it was trying to allocate huge global buffers (computed based
on the LOCAL_MEM_SIZE) and was failing.

Some Khronos basic tests were crashing with huge work group sizes.
This patch adjusts values down so that Khronos basic tests local_arg_def
and local_kernel_def can now pass.

Previously, clCreateBuffer() was using malloc to allocate buffers, which
caused havoc with NEON instructions expecting 128 bit alignment for float4
vectors.
Now, use posix_memallign() to ensure alignment meets requirements of largest
OpenCL data type (double16).
Also, update clGetDeviceInfo()'s CL_DEVICE_MEM_BASE_ADDR_ALIGN and
CL_DEVICE_MIN_DATA_TYPE_ALIGN_SIZE accordingly.

This is a continuation of the clover OpenCL project:
http://people.freedesktop.org/~steckdenis/clover
based on the contributions from Texas Instruments for Keystone II DSP device:
git.ti.com/opencl
and adding contributions from Linaro for ARM CPU-only support.
See README.txt for more info, and build instructions.
