[PATCH] D42765: [DebugInfo] Support DWARFv5 source code embedding extension

[Scott Linder via Phabricator via llvm-commits]

I addressed the API concerns in D43043 <https://reviews.llvm.org/D43043> and it's matching clang patch.

The patch breaks textual IR compatibility, but keeps the Bitcode identical. The `CSK_None` variant is gone, so there can be no ambiguity with the new `Optional`.

I also took the opportunity to make the relationship between `DIFile::ChecksumKind` and `codeview::FileChecksumKind` explicit.
