Subject: Add DK_Remark to SMDiagnostic
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=18264d1854a52e0ef36d7c17d331a6f899783a7a;p=llvm

Add DK_Remark to SMDiagnostic

Swift uses SMDiagnostic for diagnostic messages. For
https://github.com/apple/swift/pull/12294, we need remark support.

I picked the color that clang uses to display them.
