- avoid counting spaces in non-justified text

        * rendering/bidi.cpp:
        Removed file-static numSpaces.
        (WebCore::BidiState::addRun): Removed space counting.
        (WebCore::RenderBlock::computeHorizontalPositionsForLine): Added space
        counting, conditional on the block having the text-align: justify
        property value.
        (WebCore::RenderBlock::bidiReorderLine): Removed initialization of
        numSpaces.
