Reviewed by Alan Baradlay.

Reduces conditional checks in nextBreakablePosition by rearranging control flow.
(Also renames some key variables for better understandability.)

* Source/WebCore/rendering/BreakLines.h:
(WebCore::lineBreakTableUnsafeLookup): Create a table lookup inline function.
(WebCore::nextBreakablePosition): Reorganize control flow.
(WebCore::shouldBreakAfter): Deleted by incorporating into nextBreakablePosition.
(WebCore::needsLineBreakIterator): Deleted by dissolving into nextBreakablePosition.
