In the LLVM-C library, there is currently no way to get information about a DbgRecord - which is the new way to attach debug information to llvm instructions. We can only iterate on debug records with LLVMGetFirstDbgRecord/ LLVMGetLastDbgRecord/LLVMGetNextDbgRecord, but there is no way to read information. This PR adds utility functions to read DbgRecord information.
