This is needed for the ThinLTO implementation of control flow integrity, see http://lists.llvm.org/pipermail/llvm-dev/2016-October/106490.html for more details.

The R_X86_64_8 relocation type in particular is needed for 8-bit immediate operands, such as the rorl instruction's rotate count operand.
