Overall it looks ok to me, but I'd like Chandler to comment regarding the 
preferred way to do this with the new PM, since we don't tend to use booleans 
there in the PassBuilder to control passes. Is it preferable to instead use a 
new function attribute instead of boolean flags on the PMs (e.g. the way 
-fno-inline is handled)?



================
Comment at: clang/lib/Frontend/CompilerInvocation.cpp:1331
+  Opts.SplitColdCode =
+      (Opts.OptimizationLevel > 0) && (Opts.OptimizeSize != 2) &&
+      Args.hasFlag(OPT_fsplit_cold_code, OPT_fno_split_cold_code, false);
----------------
would it be appropriate to give a warning when being ignored?
