<summary>Changes</summary>
Previously we could recognize exact class tests performed by an fcmp with special values (0s, infs and smallest normal). Expand this to recognize the implied classes by a compare with a general constant. e.g. fcmp ogt x, 1 implies positive and non-0.
The API should be better merged with fcmpToClassTest but that made the diff way bigger, will try to do that in a future patch.
