We previously noted that instrumentation slots were not seen by a GC, and only implicitly rooted (by live program values) for a non-moving GC. However as part of landing debug support, we eventually had to add proper rooting; the GC now explicitly scans instrumentation slots on the stack as well as the user stackslots. So this comment is out-of-date, and moving GCs work fine with debug (which is great, because we have one now!). Fixes bytecodealliance#13798.
