136 Turn off ClipDistance and CullDistance capability checks for Vulkan.
137 - The disassembler can emit friendly names based on debug info (OpName
138 instructions), and will infer somewhat friendly names for most types.
139 This is turned on by default for the spirv-dis command line tool.

147 work in progress. The intent is to more easly report
148 and summarize functionality when SPIRV-Tools is incorporated
149 in downstream projects.
