LLJIT is a simple LLVM IR JIT. Its interface is similar to MCJIT, but its implementation is based on LLVM's newer ORC APIs. This initial patch does not make use of any of LLJIT/ORC's advanced features, but will provide better diagnostics when JIT'd code fails to link. Once LLJIT has proven usable in this basic configuration we can start experimenting with more advanced features, including lazy compilation.
