A new tool that compares TargetLibraryInfo's opinion of the availability of library function calls against the functions actually exported by a specified set of libraries. Can be helpful in verifying the correctness of TLI for a given target, and avoid mishaps such as had to be addressed in D107509 and 94b4598d. The tool currently supports ELF object files only, although it's unlikely to be hard to add support for other formats. Re-commits 62dd488 with changes to use pre-generated objects, as not all bots have ld.lld available. Differential Revision: https://reviews.llvm.org/D111358
