[Pierre-Marie de Rodat]

Type in a view conversion can be both qualified and unqualified.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

        * sem_util.adb (Is_View_Conversion): Detect qualified types.
        * sem_util.ads (Is_Actual_In_Out_Parameter): Fix style in
        comment.
