This patch is to potentially fix an assertion on debug builds by fixing a loop condition in
BidiRunList::replaceRunWithRuns to check if next run exists before accessing it.

* Source/WebCore/platform/text/BidiRunList.h:
(BidiRunList<Run>::replaceRunwithRuns): update 'while' loop
* LayoutTests/fast/text/bidi-replace-runs-crash.html: Add Test Case
* LayoutTests/fast/text/bidi-replace-runs-crash-expected.txt: Add Test Case Expectation
