[PATCH, rs6000] tighten target statements for a p8 and p9 specific tests

[Will Schmidt]

    
Hi, 
  Update the dg-requires statements for these tests to specify the target.
These tests may otherwise fail on a system missing p9 assembler support.
(Seen in a p6 environment).

OK for trunk?
Thanks,
-Will
