[verify-uselistorder] Fix a typo, fix linking

This fixes a typo from 2ef61205,
which broke the build with errors like:

    ld.lld: error: undefined symbol: LoadBitcodeIntoNewDbgInforFormat
    >>> referenced by verify-uselistorder.cpp
    >>>               tools/verify-uselistorder/CMakeFiles/verify-uselistorder.dir/verify-uselistorder.cpp.o:(main)
    >>> did you mean: LoadBitcodeIntoNewDbgInfoFormat
    >>> defined in: lib/libLLVMBitReader.a(BitcodeReader.cpp.o)
    collect2: error: ld returned 1 exit status
