Add functions to update left and right offsets to LineOffsets
https://bugs.webkit.org/show_bug.cgi?id=58028
Added update() and shrinkWidthForNewFloatIfNeeded(FloatingObject*) to LineOffsets,
which are used to update m_left and m_right. Also added m_block and m_isFirstLine
member variables to LineOffsets so that users of LineOffsets don't have to pass them around.
* rendering/RenderBlock.h:
* rendering/RenderBlockLineLayout.cpp:
(WebCore::RenderBlock::skipLeadingWhitespace): No longer passes firstLine to positionNewFloatOnLine.
(WebCore::LineOffsets::LineOffsets): Takes RenderBlock* and isFirstLine instead of left and right offsets.
(WebCore::LineOffsets::update): Extracted from findNextLineBreak and positionNewFloatOnLine.
(WebCore::LineOffsets::shrinkWidthForNewFloatIfNeeded): Extracted from positionNewFloatOnLine.
(WebCore::RenderBlock::findNextLineBreak): Calls skipLeadingWhitespace and positionNewFloatOnLine.
(WebCore::RenderBlock::positionNewFloatOnLine): Calls shrinkWidthForNewFloatIfNeeded and update and
no longer passes firstLine around.
