Andreas Kling b5a070e8ce LibJS/Bytecode: Don't create empty lexical environments 
This patch stops emitting the BlockDeclarationInstantiation instruction
when there are no locals, and no function declarations in the scope.

We were spending 20% of CPU time on https://ventrella.com/Clusters/ just
creating empty environments for no reason.
