Method traverse

deps/v8/tools/profile.mjs:1122–1135

* Traverses the call graph in preorder. This function can be used for * building optionally modified tree clones. This is the boilerplate code * for this scenario: * * callTree.traverse(function(node, parentClone) { * var nodeClone = cloneNode(node); * if (parentClone) *

(f)

   *    The second parameter is the result of calling 'f' on the parent node.
