        Move callframe initialization into JIT code, again.

        As a part of the restructuring the second result from functions is now
        returned in edx, allowing the new value of 'r' to be returned via a
        register, and stored to the stack from JIT code, too.

        4.5% progression on v8-tests. (3% in their harness)
