RFR: 8288051: Loom: Extend the compilation warning workaround in stack chunk copy

[Aleksey Shipilev]

Current builds fail on some newer GCCs and some arches. There is already a workaround in place in one copy method, we need the workaround in another one too. I took a brief look if we could dispense with this workaround altogether, but that does not seem to be straight-forward for JDK 19 timeframe.
