The branch is missed, I suppose this branch [1] is correct.

1. https://github.com/tarantool/luajit/tree/skaplun/lj-1057-arm64-stp-fusing-across-tbar

The first 2 patches are required to avoid conflicts with the last one
patch. The last patch fixes incorrect fusion of instructions across IR,
which leads to incorrect label target.
