Add Power PC ISA check to the vbit-test

The support for the Valgrind Iops is dependent on the Power processor
support for various instructions.  The instructions supported by a
given Power processor is based on the version of the ISA.  The patch
add a check to the vbit-test to ensure it does not try to test an Iop
that generates an instruction on the host that is not supported.

This patch fixes bugzilla 352765.
