    PR modula2/125544: ISO reallocate does not call allocate if the address is
NIL

    This bugfix is for the ISO Storage.REALLOCATE procedure which is a GNU
    extension.  It should behave in the same way as the PIM version by
    first checking whether the pointer parameter is NIL and then calling
    ALLOCATE.

            * gm2-libs-iso/Storage.def (REALLOCATE): Updated comment
            describing new behavior.
            * gm2-libs-iso/Storage.mod (REALLOCATE): Check addr
            and call ALLOCATE if NIL else call lowerReallocate.
            (lowerReallocate): New procedure.
