softfloat: move all default NaN definitions to softfloat.h.
These special values are needed to implement some helper functions, which return/use these values in some cases. Signed-off-by: Christophe Lyon <christophe.lyon@st.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
