Avoid use-before-definition within library unit subprograms.
tldr
The compiler now correctly inserts attribute-related subprograms for library units, preventing use-before-definition errors.

This change addresses a bug where Ada’s attribute subprograms were sometimes inserted incorrectly for library units, leading to crashes. The fix ensures that the compiler properly handles library unit subprogram bodies when generating attribute subprograms, avoiding cases where a procedure is called before its declaration is visible. This improves compiler stability and correctness when using attributes in Ada.
