cl20: Khronos Bug 16080 Fix local work size limit.

Browse Source 
Problem: Some tests assume that all local work-items can be used in a
single dimension of an NDRange.

Spec References: OpenCL C 2.0 r19, table 4.3,
CL_DEVICE_MAX_WORK_ITEM_SIZES.

Solution: The overall maximum local work size is trimmed to that of an
NDRange's first dimension or all dimensions, as appropriate.

Test Suite Affected: atomics, non_uniform_work_group, and workgroups.

Side Effects: None
