Is this logic intended to replace what was removed from CommonArgs.cpp? Should there be an assert here too?

Just didn't see the point of that assert. Can you see what the intention might be? I don't see why AddRunTimeLibs() should be callable for any/all triples, do you? I would have had to add llvm::Triple::Unknown to the list of supported OSs, which seemed strange.

I assume it was just because different OSes have different conventions for the rtlib, and if the OS is unknown and/or there's no particular support, then there might be a bug. But OTOH it doesn't seem bad to have some reasonable default either. For that matter it also seems a little weird that now we are letting the binary format be the determining thing for the Compiler-RT path. But I guess the real issue is that none of the OS, arch, or binary format is really the determining thing; it's really the toolchain/SDK or distribution of the compiler that determines what the path should be, and that can be affected by a lot of other things (e.g. is it the "system" compiler or not, is it a cross compiler, etc). So... yeah I think having this as a default makes as much sense as asserting, and when someone needs to add support for their distribution, then I suppose it's on them to refactor as needed and keep the tests working.
