Adjust ppc set_AV_CR6 computation to help Memcheck instrumentation.

* changes set_AV_CR6 so that it does scalar comparisons against zero,
  rather than sometimes against an all-ones word.  This is something
  that Memcheck can instrument exactly.

* in Memcheck, requests expensive instrumentation of Iop_Cmp{EQ,NE}64
  by default on ppc64le.
