-/**
- * The only change is in the decision to replace a LOAD_LOCAL(l)
- * in the copy-propagation performed before ClosureElimination.
- *
- * In the general case, the local variable 'l' is connected through
- * an alias chain with other local variables and at the end of the
- * alias chain there may be a Value, call it 'v'.
- *
- * If 'v' is cheaper to access (it is a Deref(This) or Const(_)), then
- * replace the instruction to load it from the cheaper place.
- * Otherwise, we use the local variable at the end of the alias chain
- * instead of 'l'.
