  Log Message:
  -----------
  [flang] Accept defined assignment with CLASS(*) RHS

A utility predicate in semantics was incorrectly determining that
an INTERFACE ASSIGNMENT(=) (or other form of generic) could not have
a specific procedure with an unlimited polymorphic second argument.
This led to a crash later in expression analysis.  Fix, and
extend tests.
