Benefit from https://github.com/llvm/llvm-project/pull/166597 and https://github.com/llvm/llvm-project/pull/164813, DWARF fission is now compatible with linker relaxation. Similar to RISC-V, this commit allows `-gsplit-dwarf` and `-mrelax` to be used together. A new test `relax_dwo_ranges.ll` same as RISC-V is also added.
