[COMMITTED] ada: Simplify iteration over record component items with possible pragmas

[Marc Poulhiès via Gcc-patches]

From: Piotr Trojanek <troja...@adacore.com>

Code cleanup; semantics is unaffected.

gcc/ada/

        * sem_util.adb (Is_Null_Record_Definition): Use First_Non_Pragma and
        Next_Non_Pragma to ignore pragmas within component list.

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