If --load-bitcode-into-experimental-debuginfo-iterators is true then debug intrinsics are auto-upgraded to DbgRecords (the new debug info format). The upgrade is trivial because the two representations are semantically identical. llvm.dbg.value with 4 operands and llvm.dbg.addr intrinsics are upgraded in the same way as usual, but converted directly into DbgRecords instead of debug intrinsics.
