  Log Message:
  -----------
  [amdgpu] Skip non-instruction values in CF user tracing.

Summary:
- CF users won't be non-instruction values. Skip them to save the
  compilation time. It's especially true when there are multiple
  functions in that module, where, says, a constant may be used in most
  functions. The current CF user tracing adds significant overhead.
