Zoltan Herczeg f5b385ca6c Tracking variables to reduce the memory consumption of scope chain. (#1819)
Currently we keep all local variables in the scope chain as long as
a nested function is alive. These variables consume memory although
several of them are never used. This patch focuses on removing those
unused ones whose can be detected at parsing time.
