PR testsuite/106879 FAIL: gcc.dg/vect/bb-slp-layout-19.c on powerpc64
On P7, option -mno-allow-movmisalign is added during testing, which
prevents slp happen on the case.
Like PR65484 and PR87306, this patch use vect_hw_misalign to guard
the case on powerpc targets.

* gcc.dg/vect/bb-slp-layout-19.c: Modify to guard the check with
vect_hw_misalign on POWERs.
