Carl Love adfd3e03b1 Valgrind, V-bit tester: Add support for Iop_CmpORD class iops ...

The Iop_CmpORD class of iops  support the POWER specific comparison
instructions.  The instructions take two 32-bit or 64-bit operands
and produce a result of the same size.  However, only the lower bits
of the result are set by the instruction.  The bits are set by the instruction
to indicate if the comparison is "less then", "greater then", or "equal".

This patch adds support to the V-bit tester to verify the propagation
of the undefined bits in the inputs to the output for the Iop_CmpORd iops.
The output bits are always set to undefined if any of the input bits are not
defined.

This patch is for bugzilla 310169
