This is a minor improvement, when printing the result of a boolean
expression. Right now, GDB prints:

    (gdb) print 1 = 2
    $1 = 0
    (gdb) print 3 = 3
    $2 = 1

The result should be of type boolean, which means either true or false.
So the expected output is:

    (gdb) print 1 = 2
    $1 = false
    (gdb) print 3 = 3
    $2 = true

The attached patches fixes it.

        * ada-lang.c (ada_evaluate_subexp): Add cases for BINOP_LOGICAL_AND,
        BINOP_LOGICAL_OR, UNOP_LOGICAL_NOT, BINOP_BITWISE_IOR,
        BINOP_BITWISE_XOR, BINOP_BITWISE_AND.
        * language.c (lang_bool_type): Add Ada case.
    
Tested on x86-linux. Checked in.

In addition, I have written a small testcase for it:

        * gdb.ada/boolean_expr.exp: New testcase.

Also tested on x86-linux. Fails without the ada-lang.c patch.
