In DWARF v5 the Line Number Program Header is extensible, allowing values with new content types. In this extension a content type is added, DW_LNCT_LLVM_source, which contains the embedded source code of the file. Add new optional attribute for !DIFile IR metadata called source which contains source text. Use this to output the source to the DWARF line table of code objects. Analogously extend METADATA_FILE in Bitcode and .file directive in ASM to support optional source. Teach llvm-dwarfdump and llvm-objdump about the new values. Update the output format of llvm-dwarfdump to make room for the new attribute on file_names entries, and support embedded sources for the -source option in llvm-objdump.
