tree-optimization/116654 - missed dr_explicit_realign[_optimized] with SLP
With single-lane SLP we miss to use the power realing loads causing
some testsuite FAILs. r14-2430-g4736ddd11874fe exempted SLP of
non-grouped accesses because that could have been only splats
where the scheme isn't used anyway, but now with single-lane SLP
it can be contiguous accesses.
PR tree-optimization/116654
* tree-vect-data-refs.cc (vect_supportable_dr_alignment):
Treat non-grouped accesses like non-SLP.
