It looks like all the changes in CodeGen are served for this. And I am a little
concerned about if it is worthy to do such a big change for this.
@efriedma-quic could you take a look here?
And I am wondering if all of the Emit*CallExpr function will be converged to
one or a few fundamental functions to emit the CallInst like `EmitCall` then we
can do our job there.
