Patch by Tamas Gergely <tgergely.u-szeged@partner.samsung.com> on 2014-01-21
Reviewed by Philip Rogers.

Source/WebCore:

In the case a SMILElement timing had a syncbase dependency on an indefinite value
the assert were raised. The assert has been removed and a check has been added
instead that prevents the addition of indefinite times to the time list.

Test: svg/animations/smil-syncbase-self-dependency.svg

* svg/animation/SVGSMILElement.cpp:
(WebCore::SVGSMILElement::createInstanceTimesFromSyncbase):
  ASSERT removed.

LayoutTests:

Test checks whether valid self-dependency is accidentally broken.

* svg/animations/smil-syncbase-self-dependency-expected.txt: Added.
* svg/animations/smil-syncbase-self-dependency.svg: Added.
