<h3>Log Message</h3>
<pre>Web Inspector: ES6: Improved Console Support for Symbol Objects
https://bugs.webkit.org/show_bug.cgi?id=141173
Reviewed by Timothy Hatcher.
Source/JavaScriptCore:
* inspector/protocol/Runtime.json:
New type, "symbol".
* inspector/InjectedScriptSource.js:
Handle Symbol objects in a few places. They don't have properties
and they cannot be implicitly converted to strings.
Source/WebInspectorUI:
* UserInterface/Protocol/RemoteObject.js:
(WebInspector.RemoteObject):
(WebInspector.RemoteObject.prototype._isSymbol):
Symbols have an objectId because it is a non-primitive that cannot be passed
by value, however it cannot have properties, so handle some cases.
* UserInterface/Views/LogContentView.css:
(.console-formatted-symbol):
Give Symbol's their own color.
LayoutTests:
* inspector/model/remote-object-expected.txt:
* inspector/model/remote-object.html:
Update the RemoteObject test to include Symbols.</pre>
