When using VM::set_variable() to put the created ScriptFunction onto a ScopeObject, we would previously unexpectedly reach the global object as set_variable() checks each traversed scope for an existing Variable with the given name - which would cause a leak of the inner function past the outer function (we even had a test expecting that behaviour!). Now we first declare functions (as DeclarationKind::Var) before setting them. This will need some more work to make hoisting across non-lexical scopes work, but it fixes this specific issue for now. Fixes #6766.
