[SystemZ][z/OS] Add GOFF Support to the DataLayout
- This patch adds in the GOFF mangling support to the LLVM data layout string. A corresponding additional line has been added into the data layout section in the language reference documentation. - Furthermore, this patch also sets the right data layout string for the z/OS target in the SystemZ backend.
