This is solved by allowing Identifier nodes to produce a Reference with
the global object as base.

67b8e6fc5b LibJS: Add Reference class to represent a base.property reference 
Expression nodes can now be asked to produce a Reference. We then use
this to implement the "delete" operator without downcasting the child
node to a MemberExpression manually.
