Sanjay Patel 8e3ef7f186 only propagate equality comparisons of FP values that we are certain are non-zero
This is a follow-on to r227491 which tightens the check for propagating FP
values. If a non-constant value happens to be a zero, we would hit the same
bug as before.

Bug noted and patch suggested by Eli Friedman.
