When SLP vectorizing we fail to mark the general alignment check
as irrelevant when using VMAT_STRIDED_SLP (the implementation checks
for itself) and when VMAT_INVARIANT the override isn't effective.
This results in extra FAILs on sparc which the following fixes.
Bootstrap and regtest running on x86_64-unknown-linux-gnu.

* tree-vect-stmts.cc (get_group_load_store_type): Properly
disregard alignment for VMAT_STRIDED_SLP and VMAT_INVARIANT.
