----------------
A bit late to the party, but can you mark this as `MarshallingInfoFlag<"LangOpts->ExpStrictFP", "false>` so that `if (Args.hasArg(OPT_fexperimental_strict_floating_point)) Opts.ExpStrictFP = true;` in CompilerInvocation.cpp gets generated automatically, we also get serializing the option for free this way.
