remove the PPCLinuxTargetAsmInfo implementation of PreferredEHDataFormat,
because it just calls the default impl. Remove the PPCDarwinTargetAsmInfo version of PreferredEHDataFormat because it just returns DW_EH_PE_absptr unless on 10.6. However, 10.6 doesn't support PPC, so the default impl is just fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77724 91177308-0d34-0410-b5e6-96231b3b80d8
