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] Add support for -force_load option The darwin linker has two ways to force all members of an archive to be loaded. The -all_load option applies to all static libraries. The -force_load takes a path to a library and just that library's members are force loaded. llvm-svn: 221477
