This marks PDT types as needing structural comparison for TBAA
if we didn't pick up a canonical variant (which we should IMHO
always do). This workaround fixes the gfortran.dg/pdt_14.f03
fail which materializes as testsuite timeout which is quite
annoying.
Bootstrap / regtest pending on x86_64-unknown-linux-gnu.
OK?

* trans-types.c (gfc_get_derived_type): When we didn't find
a canonical type mark it for structual equality.
