[PATCH] D59229: Add Swift enumerator value for CodeView::SourceLanguage

[Nathan Lanza via Phabricator via llvm-commits]

lanza created this revision.
Herald added subscribers: llvm-commits, jdoerfert.
Herald added a project: LLVM.

Swift now generates PDBs for debugging on Windows. llvm and lldb
need a language enumerator value too properly handle the output
emitted by swiftc.
