Currently we have to set 'Machine' to something in our YAML descriptions. Usually we use 'EM_X86_64' for 64-bit targets and 'EM_386' for 32-bit targets. At the same time, in fact, in most cases our tests do not need a machine type and we can use 'EM_NONE'. This is cleaner, because avoids the need of using a particular machine. In this patch I've made the 'Machine' key optional (the default value, when it is not specified is `EM_NONE`) and removed it (where possible) from yaml2obj, obj2yaml and llvm-readobj tests. There are few tests left where I decided not to remove it, because I didn't want to touch CHECK lines or doing anything more complex than a removing a "Machine: *" line and formatting lines around.
