target-ppc: Fix xscmpodp and xscmpudp instructions
- xscmpodp & xscmpudp are missing flags reset.
- In xscmpodp, VXCC should be set only if VE is 0 for signalling NaN case
and VXCC should be set by explicitly checking for quiet NaN case.
- Comparison is being done only if the operands are not NaNs. However as
per ISA, it should be done even when operands are NaNs.
