8350485: C2: factor out common code in Node::grow() and Node::out_grow()

[sarannat]

Node:grow() and Node::out_grow() are copy-pasted from each other and their core logic could be factored out into a third function or at least cleaned up. Hence,the fix includes a function Node::array_resize() that implements the core logic of Node::grow() and Node::out_grow().
