cbrt is now available in the front-end (among others), thanks again to Richard!
Closing this PR, as the optimization appears to be working fully:
$ cat a.f90
REAL*8 :: a(6),b(6)
read(*,*) a(:)
b(1)=a(1)**(1.D0/3.D0)
b(2)=a(2)**(1/3.D0)
b(3)=a(3)**(2.D0/3.D0)
b(4)=a(4)**(1/2.D0)
b(5)=a(5)**(1.D0/2.D0)
b(6)=a(6)**(3.D0/2.D0)
write(*,*) b
END
$ gfortran -O2 -ffast-math a.f90 -S
$ grep -c pow a.s
0
$ grep -c cbrt a.s
3
$ grep -c sqrt a.s
3
