Having this be a separate set of both global function attributes and different than the other fp-math attributes means it really should be called out fairly explicitly why they need to be different, what the semantics are, etc.


This makes the denormal handling consistent with the fp-math attributes. We previously had inconsistent behaviors, but now the flags should never override an existing attribute
