The code in the linux-user ARM nwfpe emulation was incorrectly
checking only for quiet NaNs when it should have been checking
for any kind of NaN. This is probably because the code in
question was taken from the Linux kernel, whose copy of the
softfloat library had been modified so that float*_is_nan()
returned true for all NaNs, not just quiet ones. The qemu
equivalent function is float*_is_any_nan(), so use that.
NB that this code is really obsolete since nobody uses FPE
for actual arithmetic now; this is just cleanup following
the recent renaming of the NaN related functions.
