This fixes an oversight in canonicalize_constructor_val which
can result in trying to add a referenced var to a function that
doesn't have them computed when folding a statement before
referenced_vars pass has been run.
Committed.
Richard.

* gimple-fold.c (canonicalize_constructor_val): Make sure
we have referenced vars setup before adding to them.
