[turbofan] Avoid using the typer's types in representation inference for phis.

Once we use type feedback, we need to reflect the feedback in the types, propagate
the new narrower types forward and use them in the subsequent
representation inference. This CL propagates and uses the recomputed types
for Phi and Select nodes (rather than using the types from the typer).
