Previously, the LineProgram objects were short-lived, and only created inside DebugInfo::prepare_lines() to create a vector of sorted LineInfo data. However, Dwarf::LineProgram also contains other useful data, such as index-to-string mapping of source directories and filenames. This commit makes each Dwarf::CompilationUnit own its Dwarf::LineProgram. DebugInfo::prepare_lines() then iterates over the compilation units to prepare its sorted vector of lines.
