target-ppc: simplify NaN propagation for vector functions

Commit e024e881bb1a8b5085026589360d26ed97acdd64 provided a pickNaN()
function for PowerPC, implementing the correct NaN propagation rules.
Therefore there is no need to test the operands manually, we can rely
on the softfloat code to do that.
