Improve the  error messages for the PPC platform to be more clear when Valgrind detects that
the underlying hardware doesn't have the needed capability.  A number of the checks for DFP
support were going to "decode_failure" instead of "decode_noDFP". These issues are also fixed.

The commit is for Bugzilla 338095
