Centralize error reporting of improper uses of incomplete types in the

new DiagnoseIncompleteType. It provides additional information about
struct/class/union/enum types when possible, either by pointing to the
forward declaration of that type or by pointing to the definition (if
we're in the process of defining that type). 
Fixes <rdar://problem/6500531>.
