With new glibc one more loop can be vectorized via simd exp in libmvec.
Found by the Linaro TCWG CI.
gcc/testsuite/ChangeLog:
* gfortran/vect/vect-8.f90: Accept more vectorized loops.

OK. At first I thought it would be good to "defend" the increase when
it's supposed to apply, but it would need a relatively complicated check,
and there should be plenty of test coverage elsewhere.
