[pushed] aarch64: Fix store_v2vec_lanes.c failure

[Richard Sandiford via Gcc-patches]

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.

Tested on aarch64-linux-gnu & pushed.

        * gcc.target/aarch64/store_v2vec_lanes.c: Add -fno-tree-vectorize.
