LibJS: Perform function instantiation in bytecode

Browse source 
This replaces Bytecode::Op::EnterScope with a new NewFunction op that
instantiates a ScriptFunction from a given FunctionNode (AST).

This is then used to instantiate the local functions directly from
bytecode when entering a ScopeNode. :^)
