[Ada] Print Storage_Pool and Procedure_To_Call fields

[Pierre-Marie de Rodat via Gcc-patches]

This makes Sprint output the Storage_Pool and Procedure_To_Call fields
of the nodes for which they are defined (allocator, free and returns).

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

gcc/ada/

        * sprint.adb (Sprint_Node_Actual) <N_Allocator>: Also print the
        Procedure_To_Call field if it is present.
        <N_Extended_Return_Statement>: Also print the Storage_Pool and
        Procedure_To_Call fields if they are present.
        <N_Free_Statement>: Likewise.
        <N_Simple_Return_Statement>: Likewise.
