Would it be better to use the RoundingMode and ExceptionBehavior enums in the ConstrainedFPIntrinsic class? These enums->strings here get turned back into those IntrinsicInst.h enums eventually anyway. But that means pulling in yet more headers in IRBuilder.h.

I admit I'm not sure what you mean with your second paragraph. Is that a way of saying that, for example, the relevant IntrinsicInst.h enums should be used instead?
