WebCore: 

Ruby did not handle malformed cases correctly when the ruby base was in
block flow. Changed the code to handle all possible cases.
Also, added some simplification methods to RenderBlock.

LayoutTests: 

Layout tests for ruby with malformed HTML.
Split up in individual tests, as well ass added a single combined test
(whose resulting render tree is probably completely different from what
you'd expect), since that combined test showed additional issues not
covered by the individual tests.
