One of many steps to generalize subprogram emission to both the DWO and non-DWO sections (to emit -gmlt-like data under fission). Once the functions are pushed down into DwarfCompileUnit some of the data structures will be pushed at least into DwarfFile so that they can be unique per-file, allowing emission to both files independently. llvm-svn: 219345
