Change message "Use of uninitialized CPU condition code" to

Change message "Use of uninitialized CPU condition code" to
"Conditional jump or move depends on uninitialised value(s)", since
that will be more meaningful to most programmers.  Also change the
suppression-kind to Cond in .supp files.  The old Value0 descriptor
means the same and is still accepted.  Suggested by Joe Buck
<Joe.Buck@synopsys.com>.
