Heschi Kreinick 0b6b5641d7 cmd/compile: use correct stack slots in location lists ... When variables need to be spilled to the stack, they usually get their own stack slot. Local variables have a slot allocated if they need one, and arguments start out on the stack. Before this CL, the debug information made the assumption that this was always the case, and so didn't bother storing an actual stack offset during SSA analysis. There's at least one case where this isn't true: variables that alias arguments. Since the argument is the source of the variable, the variable will begin its life on the stack in the argument's stack slot, not its own. Therefore the debug info needs to track the actual stack slot for each location entry. No detectable performance change, despite the O(N) loop in getHomeSlot.
