1. Verify that runtime metadata is actually valid runtime metadata when assembling, otherwise we could accept the following when assembling, but ocl runtime will reject it:

  .amdgpu_runtime_metadata
  { amd.MDVersion: [ 2, 1 ], amd.RandomUnknownKey, amd.IsaInfo:



2. Make IsaInfo optional, and always emit it.
