  -----------
  [PowerPC] Do not string pool globals that are part of llvm used. (#66848)

The string pooling pass was incorrectly pooling global varables that
were part of llvm.used or llvm.compiler.used. This patch fixes the pass
to prevent that by checking each candidate to make sure that it is not
in either of those lists.
