Have one version of libSystem for each arch. NFC. An upcoming commit will change how we choose to reference a dylib. Currently dylibs are only given an LC_LOAD_DYLIB in the final image if an atom is used. This is different from ld64 which adds the load command when the dylib is referenced on the cmdline. In order to change this behaviour, we need libSystem.yaml to actually contain a mach header so that it is parsed as a dylib, instead of currently being parsed as a normalised file. To get a mach header, we also require an arch, so now we have one libsystem per arch and all the tests have been updated to choose the correct one. llvm-svn: 278372

[mach-o] Support data-only dylibs In final linked shared images, the __TEXT segment contains both code and the mach-o header/load-commands. In the case of a data-only dylib, there is no code, so we need to force the addition of the __TEXT segment. llvm-svn: 220597
