Web Inspector: REGRESSION(r266669): DOMBreakpoint.js:106:23: CONSOLE ASSERT ERROR domNode should not change once set
https://bugs.webkit.org/show_bug.cgi?id=217865
Reviewed by Timothy Hatcher.
Source/WebInspectorUI:
* UserInterface/Models/DOMBreakpoint.js:
(WI.DOMBreakpoint.prototype.set domNode):
Adjust the assertion such that `null` is allowed if `_domNode` is already `null`.
* UserInterface/Base/Utilities.js:
(xor): Added.
Global utility function for doing a non-bitwise or that returns `false` if both values are
truthy/falsy and the truthy value if only one is truthy.
LayoutTests:
* inspector/unit-tests/utilities.html: Added.
* inspector/unit-tests/utilities-expected.txt: Added.
