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

[Scott Linder via Phabricator via llvm-commits]

This revision addresses the latest round of feedback.

Currently the filename is still included in the line table because the embedded source is acting like a cache, and just makes source available even when the original filesystem is not. For the current implementations we have in mind with the extension, there is already a valid filename to populate here.
