Reland; Pepper: Var keeps invalid var_id if VarTracker release it and there is another reference
When VarTracker remove PP_Var from VarMap, it release its Var object
if needed, but never reset var_id stored in Var object. Then, if Var's
reference count is not 1, Var continue to exist with invalid var_id until
the last reference is released.
