ac4a2da45d Strip interface tags from visible fields
The following Ada type:

   type Circle is new Shape and Drawable with record
        Center : Point;
        Radius : Natural;
   end record;

...is displayed as follow in GDB:

 (gdb) ptype circle
 type = new classes.shape with record
     V51s: ada.tags.interface_tag;
     center: classes.point;
     radius: natural;
 end record

V51s is an internal field that is of no interest for the user. It should
not be displayed.

	* ada-lang.c (ada_is_interface_tag): New function.
	(ada_is_ignored_field): Add interface tags to the list
	of ignored fields.

b50d69b5aa Full view of interface-wide types
For displaying the full view of a class-wide object, GDB relies on
the assumption that this view will have the same address as the
address of the object. In the case of simple inheritance, this
assumption is correct; the proper type is deduced by decoding
the tag of the object and converting the result to this full-view
type.

Consider for example an abstract class Shape, a child Circle
which implements an interface Drawable, and the corresponding
following objects:

   My_Circle   : Circle := ((1, 2), 3);
   My_Shape    : Shape'Class := Shape'Class (My_Circle);
   My_Drawable : Drawable'Class := Drawable'Class (My_Circle);

To display My_Shape, the debugger first extracts the tag (an internal
field, usually the first one of the record):

 (gdb) p my_shape'address
 $2 = (system.address) 0x8063e28
 (gdb) x/x my_shape'address
 0x8063e28 <classes__my_shape>: 0x08059ec4

Then the type specific data and the expanded name of the tag is read
from there:

 (gdb) p my_shape'tag
 $3 = (access ada.tags.dispatch_table) 0x8059ec4 (classes.circle)

To get the full view, the debugger converts to the corresponding type:

 (gdb) p {classes.circle}0x8063e28
 $4 = (center => (x => 1, y => 2), radius => 3)

Now, in the case of multiple inheritance, the assumption does not hold
anymore. The address that we have usually points to some
place lower. The offset to the original address is saved in the field
Offset_To_Top of the metadata that are above the tag, at address
obj'tag - 8. In the case of my_shape, this offset is 0:

 (gdb) x/x my_shape'tag - 8
 0x8059ebc <classes__circleT+12>:        0x00000000

...but in the case of an interface-wide object, it is not null:

 (gdb) x/x my_drawable'tag - 8
 0x8063b28 <classes__classes__circle_classes__drawable1T56s+12>: 0x00000004
 (gdb) p {classes.circle}(my_drawable'address - 4)
 $7 = (center => (x => 1, y => 2), radius => 3)

The following change handles this relocation in the most common cases.
Remaining cases that are still to be investigated are signaled by
comments.

	* ada-lang.h (ada_tag_value_at_base_address): New function
	declaration.
