Herald added a project: LLVM.

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 tried to reusing techniques used in the ELF
linker (see `lld/ELF/InputSections.h`).
