Check_Limited_Return originally used Comes_From_Source (N) in order to
decide whether N was a return statement created from an extended return
statement or not.
This was a problem because the return statement from expression
functions also have their Comes_From_Source flag set to false.
The solution is to use Comes_From_Extended_Return_Statement to decide
whether to post error messages or not.
