    [Ada] Fix strange behavior of Object_Size for packed array subtype

    gcc/ada/

            * gcc-interface/decl.c (gnat_to_gnu_entity) <discrete_type>: Do not
            deal with the ___XP suffix for packed array types here...
            <E_Array_Subtype>: ...or here when processing the implementation
type
            but when processing the original type instead.  Do not reuse the
DECL
            of the implementation type for the original type.  Tidy up.

    [gdb/testsuite] Add xfail for PR gcc/101643

    With gcc 8.5.0 I run into:
    ...
    (gdb) print bad^M
    $2 = (0 => 0 <repeats 25 times>)^M
    (gdb) FAIL: gdb.ada/big_packed_array.exp: scenario=minimal: print bad
    ...
    while with gcc 9.3.1 we have instead:
    ...
    (gdb) print bad^M
    $2 = (false <repeats 196 times>)^M
    (gdb) PASS: gdb.ada/big_packed_array.exp: scenario=minimal: print bad
    ...

    This is caused by gcc PR, which I've filed at
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101643 "[debug, ada] packed
array
    not described as packed".

    Fix by marking this as XFAIL.

    Tested on x86_64-linux.
