Implement NonSemantic.Shader.DebugInfo.100 debug instruction generation.

These instructions will be generated under the -gV and -gVS  command line options. These instructions enable source-level shader debugging with Renderdoc.

This is an alpha release of this capability. Additional improvements are forthcoming. Use and feedback are welcome.
