[Ada] Annotate GNAT.Sockets with No_Return aspects
Opportunity for extra annotations spotted while fixing detection of
unreachable code that follows calls to procedures annotated with
No_Return.
gcc/ada/
* libgnat/g-socket.adb (Raise_Host_Error): Add No_Return aspect.
(Raise_GAI_Error): Likewise.
* libgnat/g-socket.ads (Raise_Socket_Error): Likewise.
