RFR 8130853: Non-extensible global is not handled property

[Hannes Wallnoefer]

addBoundProperty on Global.LexicalScope should always be called with 
true as extensible parameter (or call its super-method with 
extensible=true). LexicalScope is a declarative environment record added 
to the "normal" global object environment record for let-const 
declarations, and it can't be frozen or made non-extensible.

A minor issue: ScriptObject#addBoundProperty javadoc for extensible 
param says "whether the source object is extensible or not", but it's 
really whether the current object is extensible or not.
