I now realize that Erik Österlund's work does cover this, and much much
more, and have already withdrawn the related bugs, and do also withdraw
this RFR. I'll focus my GC interface work on non-BarrierSet related
issues and areas where I can help fill in the BarrierSet (aarch64,
finding barrier sites for primitive loads/stores etc).
