        Bundle lineLeftOffset and lineRightOffset as a class
        https://bugs.webkit.org/show_bug.cgi?id=57851

        Added a new class LineOffsets that encapsulates lineLeftOffset and lineRightOffset.
        The patch makes clear that lineLeftOffset and lineRightOffset are never read individually
        and only the difference is used to compute the width.

        * rendering/RenderBlock.h:
        * rendering/RenderBlockLineLayout.cpp:
        (WebCore::RenderBlock::skipLeadingWhitespace): Takes LineOffsets instead of two integers.
        (WebCore::LineOffsets::LineOffsets): Added.
        (WebCore::LineOffsets::width): Added.
        (WebCore::LineOffsets::setLeft): Added.
        (WebCore::LineOffsets::setRight): Added.
        (WebCore::RenderBlock::findNextLineBreak): Calls skipLeadingWhitespace and positionNewFloatOnLine.
        (WebCore::RenderBlock::positionNewFloatOnLine): Takes LineOffsets instead of two integers.
