    aarch64: Fix store_v2vec_lanes.c failure
    
    store_v2vec_lanes.c started failing after SLP was enabled at -O2.
    The test is specifically checking what happens for unvectorised code,
    with the vectors being constructed from individal addition results.
    
    gcc/testsuite/
            * gcc.target/aarch64/store_v2vec_lanes.c: Add -fno-tree-vectorize.
