[PATCH] D76831: [AST] Preserve the DeclRefExpr when it refers to an invalid decl.

[Sam McCall via Phabricator via cfe-commits]

sammccall added a comment.

I like the idea, but it seems to regress quite a lot of diagnostics... e.g. where we fail to deduce auto and then say it's not a pointer.

Also this is regressing things in the -fno-recovery-ast case, because of the changes to CheckDeclInExpr with the existing callsites that allow invalid decls. (I'm not sure what passing AcceptInvalid actually *did* before)
