[COMMITTED] ada: Fix wrong optimization of extended return for discriminated record type

[Marc Poulhiès via Gcc-patches]

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

This happens when the discriminants of the record type have default values.

gcc/ada/ChangeLog:

        * inline.adb (Expand_Inlined_Call): In the case of a function call
        that returns an unconstrained type and initializes an object, set
        the No_Initialization flag on the new declaration of the object.

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