Michael Liao cc92833f8a [amdgpu] Remove the GlobalDCE pass prior to the internalization pass. ...

- In [D98783](https://reviews.llvm.org/D98783), an extra GlobalDCE pass
  is inserted before the internalization pass to ensure a global
  variable without users could be internalized even if there are dead
  users. Instead of inserting a dedicated optimization pass, the
  dead user checking, i.e. 'use_empty()', should be preceeded with
  constant dead user removal to ensure an accurate result.
