Research direction
Start by locating spv_ext_inst_desc_t and the validation path for SPV_AMD_gcn_shader. Trace how extended-instruction capability dependencies are represented, then determine where an extension dependency must be recorded and validated. Done means the extension-dependent instruction is represented and SPV_AMD_gcn_shader validation succeeds.
