Timings in 4.4 are essentially unchanged

gfortran -O3 -ffast-math -march=native PR25621.f90:

 default loop   1.2920810000000000
 hand optimized loop  0.86405399999999988

fun enough inverse timings with a recent intel compiler:

 default loop  0.440028000000000
 hand optimized loop   1.26007800000000
