[DWARFv5] CodeGen support for MD5 file checksums Pass MD5 checksums through from IR to assembly/object files. After this, getting Clang to compute the MD5 should be the last step to supporting MD5 in the DWARF v5 line table header. Differential Revision: https://reviews.llvm.org/D41926 llvm-svn: 322391

[DWARFv5] Tolerate files not all having an MD5 checksum. In some cases, for example when compiling a preprocessed file, the front-end is not able to provide an MD5 checksum for all files. When that happens, omit the MD5 checksums from the final DWARF, because DWARF doesn't have a way to indicate that some but not all files have a checksum. When assembling a .s file, and some but not all .file directives provide an MD5 checksum, issue a warning and don't emit MD5 into the DWARF. Fixes PR37623.

DWARF v5 specifies that the root file (also given in the DW_AT_name attribute of the compilation unit DIE) should be emitted explicitly to the line table's list of files. This makes the line table more independent of the .debug_info section. We emit the new syntax only for DWARF v5 and later. Fixes the bug found by asan.

[DebugInfo] Support DWARF v5 source code embedding extension 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.
