Description Ryosuke Niwa 2013-12-16 18:42:51 PST 
Consider merging https://chromium.googlesource.com/chromium/blink/+/02bca0ac6f09e150df9f8bf210959cc4112322a1

Currently Blink creates a fake run for a given isolated span once during each call
to createBidiRunsForLine. However in some cases the added fake run is not necessary.

This patch uses the same logic in RenderBlockFlow::appendRunsObject to create
fake runs just when they are really needed.
