Port b83c3d29

Original Commit Message:

    When a function is declared in global scope, the closure is created
    by the DeclareGlobals runtime service. It needs a pointer to the
    literals array, already allocated in the feedback vector. This
    fixes a bug where it's behavior wasn't in sync with CreateClosure,
    which accepts the literals from the vector.

    This enables a follow-on performance improvement in the CompileLazy
    builtin.
