Sanjay Patel e571983e6c [ValueTracking, InstSimplify] extend isKnownNonZero() to handle vector constants ...

Similar in spirit to D20497 :
If all elements of a constant vector are known non-zero, then we can say that the
whole vector is known non-zero.

It seems like we could extend this to FP scalar/vector too, but isKnownNonZero()
says it only works for integers and pointers for now.
