The CL CTS queries CL_DEVICE_MEM_BASE_ADDR_ALIGN for a device, and
then allocates user pointers aligned to that value for tests.
The minimum value is defined as:
the size (in bits) of the largest OpenCL built-in data type supported
by the device (long16 in FULL profile, long16 or int16 in EMBEDDED
profile) for devices that are not of type CL_DEVICE_TYPE_CUSTOM.
