This undoes an ancient optimization in LLVM to support RISC-V's desire
to over-emit relocations for link time relocation relaxation. This also
removes the adhoc handling of symbolic difference handling for RISCV,
localising all the RISC-V specific behaivour to the target rather than
keeping it at the global level.
