  -----------
  [flang] Fix crash in semantics after PDT instantiation

The code in semantics that reinitializes symbol table pointers in
the parse tree of a parameterized derived type prior to a new
instantiation of the type was processing the symbols of the
derived type instantiation scope in arbitrary address order,
which could fail if a reference to a type parameter inherited from
an ancestor type was processed prior to the parent component sequence.
Fix by instantiating components of PDT instantiations in declaration
order.
