This adds support for LLVM IR "objects" within universal MachO, as this can append when using LTO when compiling iOS/tvOS applications (or any universal MachO object compiled with clang).

This also improve llvm-lipo in order to support these LLVM IR objects. llvm-lipo is know able to extract, create and dump information for universal MachO with LLVM IR bitcode objects.

One strategy to test this properly would require implementing LLVM IR description within the ObjectYAML library. Before doing so, I would like to here about other potential strategy!
