This adds methods to verify the chunk metadata very GC in debug builds (held relocated arenas mess things up because they're mprotected so it's checked after we free those). The code in question was hard to exercise and I had to update reportLargeAllocationFailure to take a byte count so we could avoid calling the shell's large allocation failure callback, which causes the shell to exit (see JSRuntime::onOutOfMemoryCanGC). It's debateable whether it's worth handling OOM from MarkPagesUnusedSoft. If we assume pages have been been successfully marked unused regardless of failure I think the worst that happens is that we don't reuse them immediately... I ended up handling this anyway though, and rebuilding the list rather than clearing it entirely in decommitFreeArenasWithoutUnlocking.
