Serguei Katkov 297ec61130 [IsKnownNonZero] Handle the case with non-constant phi nodes 
Handle the case when all inputs of phi are proven to be non zero.

Constants are checked in beginning of this method before check for depth of recursion,
so it is a partial case of non-constant phi.

Recursion depth is already handled by the function.
