Description Chris Dumez 2015-09-17 09:44:28 PDT
Add support for default parameter values to our Web IDL parser / JS bindings generator. This will allow the bindings to convert undefined to the parameter's default value for optional parameters:
https://heycam.github.io/webidl/#dfn-optional-argument-default-value

Initially, this will be used for document.createNodeIterator() / document.createTreeWalker()'s whatToShow parameter:
https://dom.spec.whatwg.org/#document

WebKit currently converts undefined to 0 in this case, even though it should be OxFFFFFFFF.
