ELFRelocationEntry::operator<(): Try to stabilize the order. r_offset was insufficient to sort Relocs.
It should fix llvm/test/CodeGen/ARM/ehabi-mc-compact-pr*.ll on some hosts.
RELOCATION RECORDS FOR [.ARM.exidx]:
0 R_ARM_PREL31 .text
0 R_ARM_NONE __aeabi_unwind_cpp_pr0
FIXME: I am not sure of the directions of extra comparators, in Type and Index.
For now, they are different from the direction in r_offset.
