  Log Message:
  -----------
  AMDGPU: Don't consider whether amdgpu-flat-work-group-size was set

It should be semantically identical if it was set to the same value as
the default. Also improve the documentation.

  Log Message:
  -----------
  AMDGPU: Use attributor to propagate amdgpu-flat-work-group-size

This can merge the acceptable ranges based on the call graph, rather
than the simple application of the attribute. Remove the handling from
the old pass.
