[flang] Check for undefined derived types
It's possible to specify refer to an undefined derived type as the type of a
component of another derived type and then never define the type of the
component. We were not detecting this situation. To fix this, I
changed the value of isForwardReferenced_ in the symbol's
DerivedTypeDetails and checked for it when performing other derived type
checks.
I also had to record the fact that error messages were previously
emitted for the same problem in some cases so that I could avoid
duplicate messages.
I also added a test.
