[Ada] whatis not printing array type name for value from history

Consider the following declaration:

   type Full_Table is array (Color) of Integer;
   Full : Full_Table := (144, 233, 377, 610, 987);

The debugger correctly prints the type name of variable "full":

        (gdb) whatis full
        type = pck.full_table

But is unable to do so when using the value history:

        (gdb) print full
        $1 = (144, 233, 377, 610, 987)
        (gdb) whatis $
 !!! -> type = array (black .. white) of integer

This is because the evaluation creates a "fixed" version of
the array type, and that "fixed" version is missing a type name.
As a result, whatis falls back to describing the type (a la ptype)
instead of printing the type name.

gdb/ChangeLog:

        * ada-lang.c (to_fixed_array_type): Set result's type name.

gdb/testsuite/ChangeLog:

        * gdb.ada/whatis_array_val: New testcase.
