[CI-NOTIFY]: TCWG Bisect tcwg_bmk_tx1/gnu-master-aarch64-spec2k6-O2_LTO - Build # 16 - Successful!
Successfully identified regression in *gcc* in CI configuration tcwg_bmk_gnu_tx1/gnu-master-aarch64-spec2k6-O2_LTO. So far, this commit has regressed CI configurations: - tcwg_bmk_gnu_tx1/gnu-master-aarch64-spec2k6-O2_LTO

Run pass_sink_code once more before store_merging
Gimple sink code pass runs quite early, there may be some new oppertunities exposed by later gimple optmization passes, this patch runs the sink code pass once more before store_merging. For detailed discussion, please refer to: https://gcc.gnu.org/pipermail/gcc-patches/2020-December/562352.html
Tested the SPEC2017 performance on P8LE, 544.nab_r is improved by 2.43%, but no big changes to other cases, GEOMEAN is improved quite small with 0.25%.
