  Log Message:
  -----------
  [flang] Better error messages & more cases caught for bad forward refs

Subclause 10.1.12 in F'2018 prohibits forward references from
a specification expression to an object declared later in the
same specification part.  Catch this error better and emit
specific error messages about the violation.
