[PowerPC] Fix reversed bit issue in DCMX mask for "xvtstdcdp" and "xvtstdcsp" P9 implementation
Did experiments on power 9 machine, checked the outputs for NaN & Infinity+
cases with corresponding DCMX bit set. Confirmed the DCMX mask bit for NaN and
infinity+ are reversed.
This patch fixes the issue.
Patch by Victor Huang.
