[commit/Ada] Fix ada array bounds display

[Joel Brobecker <brobecker at adacore dot com>]

Array bounds were not correctly displayed when the SHOW parameter of
print_type functions is set to -1.  This shows up in the following
type of situation, where we have a declaration as follow:

    Anon_Array_Int_Obj : array (1..10) of Integer := (others => 8);

In GDB/MI mode, trying to print the type info for our array object
yields:

    (gdb) -var-create ai 0 Anon_Array_Int_Obj
    (gdb) -var-info-type ai
    ^done,type="array (...) of integer"

The actual bounds are missing.  Contrast this with what happens
when in GDB/CLI mode:

    (gdb) ptype Anon_Array_Int_Obj
    type = array (1 .. 10) of integer

This patch fixes array type printing accordingly. And as it turns
out, it also improves the output for one of the tests already present,
so it shows that it's not just the GDB/MI mode that's affected.

gdb/ChangeLog (Jean-Charles Delay):

	* ada-typeprint.c (print_array_type): removed if condition on show
	being negative for bounds printing.

gdb/testsuite/ChangeLog (Jean-Charles Delay):

	* gdb.ada/packed_array.exp: fixed expected output.

Tested on x86_64-linux.  Checked in.
