Print a translation unit.

Signature
(print-transunit tunit pstate) → new-pstate
Arguments: tunit — Guard (transunitp tunit).; pstate — Guard (pristatep pstate).
Returns: new-pstate — Type (pristatep new-pstate).

We ensure that there is at least one external declaration, as required by the grammar.
