Sanjay Patel 94a9f57861 [InstCombine] Without infinites, fold (C / X) < 0.0 --> (X < 0) ...

When C is not zero and infinites are not allowed (C / X) > 0 is a sign
test. Depending on the sign of C, the predicate must be swapped.

E.g.:
  foo(double X) {
    if ((-2.0 / X) <= 0) ...
  }
 =>
  foo(double X) {
    if (X >= 0) ...
  }
