A 64-bit label difference `.quad A-B` is directly expressable on Mach-O and RISC-V (`R_RISCV_SUB*`) and can be converted to PC-relative on ELF. For example, mips64 supports 64-bit PC-relative since D80390 <https://reviews.llvm.org/D80390> (GNU as still doesn't allow it) => this allowed an XRay clean-up D87977 <https://reviews.llvm.org/D87977>.
