SV_GroupID (in clang, SV_GroupIndex) isn't supported in the example you
provided because FieldDecls aren't currently defined as appropriate subjects
for the annotation to appertain to. Only ParmVars and GlobalVars.
As of right now, SV_DispatchThreadID is the only semantic value annotation that
has been defined in Attr.td, that can appertain to Field Decls.
