vec_store_lanes{oi,ci,xi}_lane are not standard pattern names, so using them in 
aarch64-simd.md is misleading. This adds an aarch64_ prefix to those pattern 
names, paralleling aarch64_vec_load_lanes<mode>_lane.

bootstrapped and check-gcc on aarch64-none-linux-gnu

gcc/ChangeLog:

        * config/aarch64/aarch64-simd.md (vec_store_lanesoi_lane<mode>): Rename
        to...
        (aarch64_vec_store_lanesoi_lane<mode>): ...this.

        (vec_store_lanesci_lane<mode>): Rename to...
        (aarch64_vec_store_lanesci_lane<mode>): ...this.

        (vec_store_lanesxi_lane<mode>): Rename to...
        (aarch64_vec_store_lanesxi_lane<mode>): ...this.

        (aarch64_st2_lane<VQ:mode>, aarch64_st3_lane<VQ:mode>,
        aarch64_st4_lane<VQ:mode>): Follow renaming.
