[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

; MD5 checksums provided by IR should be passed through to asm.
; They'll be emitted to an object file only for DWARF 5 or later.

Reapply "[DWARFv5] Emit file 0 to the line table." 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. Fixes the bug found by asan. Also XFAIL the new test for Darwin, which is stuck on DWARF v2, and fix up other tests so they stop failing on Windows.

[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.
