    [Ada] Error adding/subtracting pointer value to/from integral.
    
    When trying to evaluate an expression which adds a pointer and
    an integral, the evaluation succeeds if the pointer is on
    the left handside of the operator, but not when it is on the right
    handside:
    
        (gdb) p something'address + 0
        $1 = (system.address) 0x613418 <pck.something>
        (gdb) p 0 + something'address
        Argument to arithmetic operation not a number or boolean.
    
    Same issue when doing subtractions:
    
        (gdb) p something'address - 0
        $2 = (system.address) 0x613418 <pck.something>
        (gdb) p 0 - something'address
        Argument to arithmetic operation not a number or boolean.
    
    This patch enhances the Ada expression evaluator to handle
    these two situations.
    
    gdb/ChangeLog:
    
            * ada-lang.c (ada_evaluate_subexp) <BINOP_ADD>: Add handling
            of the case where the second operand is a pointer.
            <BINOP_SUB>: Likewise.
    
    gdb/testsuite/ChangeLog:
    
            * gdb.ada/addr_arith: New testcase.
    
    Tested on x86_64-linux.
