RFR 8047728: (function(x){var o={x:0}; with(o){delete x} return o.x})() evaluates to 0 instead of undefined

A comment above the line

+            final boolean failDelete = strictMode || (!symbol.isScope() && (symbol.isParam() || (symbol.isVar() && !symbol.isProgramLevel())));

explaining the logic, would be helpful, I guess. It is getting a bit convoluted.


Can you add a TODO in the comment in LocalVariableTypesCalculator so it shows up in the margin of IDEs?
