Looks good with one cleanup.



================
Comment at: lib/Frontend/CompilerInvocation.cpp:2177-2178
 
+  if (const Arg *A = Args.getLastArg(OPT_fdigraphs, OPT_fno_digraphs))
+    Opts.Digraphs = A->getOption().matches(OPT_fdigraphs) ? 1 : 0;
+
----------------
Simplify this to `Opts.Digraphs = Args.hasFlag(OPT_fdigraphs, OPT_fno_diagraphs, Opts.Digraphs);`
