Native code raise to MIR?

I've heard several questions lately about Phoenix's ability to raise native code to MIR (Phx.FunctionUnit.SymbolicFunctionUnitState).  Today Phoenix does not support raising native code to MIR.  We do plan to support raising beyond LIR in the future for native code, but at this moment in time it is just LIR. 

Note that we can raise managed code to Phx.FunctionUnit.SymbolicFunctionUnitState.
