--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The gfortran.dg/vect/vect-8.f90 testcase is incredibly bad because it has so
many loops that are or are not vectorized.  It should ideally be split up.

But I think the blame is incorrect, the test uses
-fno-tree-loop-distribute-patterns and thus isn't effected by the rev in
question.

As Andrew says the fix for the other regression is trivial, I'm leaving that
to ARM folks as an exercise.
