* sem_ch5.adb (Analyze_Iterator_Specification): Diagnose
various illegalities in iterators over arrays and containers:
a) New function Get_Cursor_Type, to verify that the cursor is
not a limited type at the point of iteration.
b) If the container is a constant, an element_iterator is illegal
if the container type does not have a Constant_Indexing aspect.
c) If the iterate function has an in-out controlling parameter,
the container cannot be a constant object.
d) Reject additional cases of iterators over a
discriminant-dependent component of a mutable object.
