[Ada] do not print arrays as array pointers
This patch enhances the debugger to distinguish between fat pointers
that represent either: array types, or array access types. In the latter
case, the object/type is encoded as a typedef type pointing to the fat
pointer.
The first part of the change is to adjust ada_check_typedef to avoid
stripping the typedef layer when it points to a fat pointer. The rest
of the patch is adjustments required in various places to deal with
the fact that the type is uses might now be a typedef.
gdb/ChangeLog:
* ada-lang.h (ada_coerce_to_simple_array): Add declaration.
* ada-lang.c (ada_typedef_target_type): New function.
(desc_base_type): Add handling of fat pointer typedefs.
(ada_coerce_to_simple_array): Make non-static.

Add assertion.

* ada-typeprint.c (ada_print_type): Add handling of fat pointer
typedefs.
* ada-valprint.c (ada_val_print_1): Convert fat pointers that are not
array accesses to simple arrays rather than simple array pointers.
(ada_value_print): In the case of array descriptors, do not print
the value type description unless it is an array access.

sim: HW_NALLOC: new alloc helper
We have malloc (uninitialized buffer), zalloc (zeroed buffer), and
nzalloc (zeroed array). But we don't have a way to allocate an
uninitialized array. Add a HW_NALLOC to fill this gap.

sim: HW_NZALLOC: fix arg handling
The HW_NZALLOC macro has all caps args for some reason (unlike the other
alloc helpers), and ends up not using the "ME" argument since its copy
and paste source uses "me". Make all the args lowercase to match the
style of all the other args and make it use the correct "me".
