for TLS dynamic models on 64-bit PowerPC ELF. The default sort routine for relocations only sorts on the r_offset field; but with TLS, there can be two relocations with the same r_offset. For PowerPC, this patch sorts secondarily on descending r_type, which matches the behavior expected by the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170237 91177308-0d34-0410-b5e6-96231b3b80d8
