fix missing barrier instructions in mips atomic asm
previously I had wrongly assumed the ll/sc instructions also provided
memory synchronization; apparently they do not. this commit adds sync
instructions before and after each atomic operation and changes the
atomic store to simply use sync before and after a plain store, rather
than a useless compare-and-swap.
(cherry picked from commit bcad48439494820989f5867c3f8ccfa6aae2909f)
