[COMMITTED] ada: Fix handling of constrained array declarations in declare-expression

[Marc Poulhiès via Gcc-patches]

From: Eric Botcazou <ebotca...@adacore.com>

They need to go through Constrain_Array or else they do not really work.

gcc/ada/

        * sem_ch3.adb (Find_Type_Of_Object): In a spec expression, also set
        the Scope of the type, and call Constrain_Array for array subtypes.

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