The entire following paragraph. "Unlike the IEEE-754 2008 behavior, this does not distinguish between
signaling and quiet NaN inputs. If a target's implementation follows
the standard and returns a quiet NaN if either input is a signaling
NaN, the intrinsic lowering is responsible for quieting the inputs to
correctly return the non-NaN input (e.g. by using the equivalent of
``llvm.canonicalize``)."

This is not returning an "always quiet nan" and matches the libm behavior
