Adopt new cl::HideUnrelatedOptions API added r226729.

Summary: cl::HideUnrelatedOptions allows tools to hide all options not part of a specific OptionCategory. This is the common use case for cl::getRegisteredOptions, which should be deprecated in the future because it exposes implementation details of command line parsing.
