Sanjay Patel 4ec7c02197 [InstSimplify] fix bug in poison propagation for FP ops ...

If any operand of a math op is poison, that takes
precedence over general undef/NaN.

This should not be visible with binary ops because
it requires 2 constant operands to trigger (and if
both operands of a binop are constant, that should
get handled first in ConstantFolding).
