[COMMITTED 22/30] ada: Crash checking accessibility level on private type

[Marc Poulhiès]

From: Justin Squirek <squi...@adacore.com>

This patch fixes an issue in the compiler whereby calculating a static
accessibility level on a private type with an access discriminant resulted
in a compile time crash when No_Dynamic_Accessibility_Checks is enabled.

gcc/ada/

        * accessibility.adb (Accessibility_Level): Use Get_Full_View to
        avoid crashes when calculating scope.

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