The main motivation for this refactor is to remove the subclass relationship between the InputSegment and MergeInputSegment and SyntenticMergedInputSegment so that we can use the merging classes for debug sections which are not data segments. In the process of refactoring I also remove all the virtual functions from the class hierarchy and try to reuse techniques used in the ELF linker (see `lld/ELF/InputSections.h`).
