  Log Message:
  -----------
  [HIP] Make sure, unused hip-pinned-shadow global var is kept within device code

Summary:
hip-pinned-shadow global var should remain in the final code object irrespective
of whether it is used or not within the code. Add it to used list, so that it
will not get eliminated when it is unused.
