Yes, what I am really after is a way to configure codegen when using LLVM via the LTO library. At the moment I cannot do so.

The lto_codegen_debug_options() function does allow me to pass options in and does result in these options being parsed using cl::ParseCommandLineOptions() -- the problem is, without this patch, these options do not get applied, which I think is an issue for anyone trying to debug LTO.dll using lto_codegen_debug_options().
