In DWARF v5 the Line Number Program Header is extensible, allowing values with new content types. This vendor extension to DWARF v5 allows source text to be embedded directly in the line tables of the debug line section. Add new flag (-g[no-]embed-source) to Driver and CC1 which indicates that source should be passed through to LLVM during CodeGen.
