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.
