Unfortunately, this is due to my screw up.  The patch to fix the
vec_mule and vec_mulo was missing the test case update.  I made the
change to the test case but didn't get it included in the patch.  I have
since fixed the above failures, commit 249572.  The commit was tested on
Power 8 BE, LE and Power 7 to make sure they are all working now.

The other tests listed, gcc.c-torture/execute/* and gcc.dg/vect/* I have
never touched so I don't think I am responsible for those.  :-)
