[COMMITTED 02/30] ada: Add assertion on expanded code in particular case

[Marc Poulhiès]

From: Ronan Desplanques <desplanq...@adacore.com>

This patch adds an assertion that checks that expanded code does not
contain erroneous access subtype definitions.

gcc/ada/ChangeLog:

        * sem_ch3.adb (Process_Subtype): Add assertion.

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