Test that calc values in transitions don't lead to a style resolution spin.
PASS
Style resolution spin due to calc() values always comparing inequal (seen on arstechnica.com) https://bugs.webkit.org/show_bug.cgi?id=179982 <rdar://problem/35677991> Reviewed by Darin Adler. Source/WebCore: Test: transitions/transition-with-calc-spin.html Something like calc(100% - 10px) would compare inequal to itself. This causes the implicit animation engine think that there is a new target value after style resolution and restart the transition. Starting the transition triggers another style resolution on zero duration timer and so on. * platform/CalculationValue.cpp: (WebCore::operator==): * platform/CalculationValue.h: Deep compare the child vectors.
