Summary: This will handle expansion of C++ fragments in the declarative combiner including custom predicates, and escapes into C++ to aid the migration effort. Fixed the -DLLVM_LINK_LLVM_DYLIB=ON using DISABLE_LLVM_LINK_LLVM_DYLIB when creating the library. Apparently it automatically links to libLLVM.dylib and we don't want that from tablegen.
