Hi,
This is another vect case which requires special handling with
vect_hw_misalign. The alignment of the second part requires
misaligned vector access supports. This patch is to adjust
the related guard condition and comments.
Verified it on ppc64-redhat-linux (Power7 BE).
Is it ok for trunk?
BR,
Kewen

non-vect_hw_misalign targets.
