[PATCH] vect: Use vect_relevant_for_alignment_p consistently

[Yangfei (Felix)]

Hi,

  Noticed two places in tree-vect-data-refs.c where we can use function 
vect_relevant_for_alignment_p.
  Looks like these two are missed when we were introducing the function.
  Bootstrapped and tested on aarch64-linux-gnu.  OK to go?

  ChangeLog modification is contained in the patch.

Thanks,
Felix
