[Marc Poulhiès via Gcc-patches]

From: Bob Duff <d...@adacore.com>

Proc_Next_Component_Or_Discriminant was duplicating the code
in Next_Component_Or_Discriminant.

gcc/ada/

        * einfo-utils.adb:
        (Proc_Next_Component_Or_Discriminant): Call
        Next_Component_Or_Discriminant.

Tested on x86_64-pc-linux-gnu, committed on master.
