Summary: Some targets support denormals as floating point exceptions. This is provided as an extension in the GNU headers as __FE_DENORM. This provides it in our headers, however I'm unsure if we should make it internal or external. I do not think it should be in all exception as it doesn't represent an exceptional behavior as far as the standard is concerned, but I'm not an expert.
