tree-optimization/110614 - SLP splat and re-align (optimized)

The following properly guards the re-align (optimized) paths used
on old power CPUs for the added case of SLP splats from non-grouped
loads.  Testcases are existing in dg-torture.

PR tree-optimization/110614
* tree-vect-data-refs.cc (vect_supportable_dr_alignment):
SLP splats are not suitable for re-align ops.
