It should be easy to extract the signatures, and mix them into RuntimeLibcallsInfo. (I assume it is mostly pattern matching. I used a couple of sed expressions to go from .def to .td.) Of course, there are lot of functions in RuntimeLibcallsInfo which are not in TargetLibraryInfo, requiring manual effort to add a type signature (if needed).
