I've just seen the proposed patch posted, which explains these instructions
should only trap in the presence of signaling NaNs. So I believe the correct
test sould be !(flag_trapping_math && flag_signaling_nans). Unfortunately,
this still means you need to use -Ofast (or equivalent) to generate these
instructions.
