Document Table of Contents Omit Hardware to Support the global_work_offset Argument in the clEnqueueNDRangeKernel API

The uses_global_work_offset(0) kernel attribute instructs the Intel® FPGA SDK for OpenCL™ Offline Compiler to omit hardware required to support a non-zero or non-NULL global_work_offset argument in NDRange kernels.

This kernel attribute is recommended for all kernels that are always enqueued with a zero or NULL global_work_offset argument. When this kernel attribute is set, the Intel FPGA host runtime returns with CL_INVALID_GLOBAL_OFFSET error code if a non-zero or non-null global_work_offset argument is used to enqueue the kernel.
