Log message:
	[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.
	(decode_packed_array_bitsize): Add handling of fat pointer typedefs.
	Add assertion.
	(ada_template_to_fixed_record_type_1, ada_to_fixed_type)
	(ada_check_typedef): Add handling of fat pointer typedefs.
	(ada_evaluate_subexp) [OP_FUNCALL]: Likewise.
	* 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.
	
	gdb/testsuite/ChangeLog:
	
	* gdb.ada/lang_switch.exp: Correct expected parameter value.
	
	gdb/doc/ChangeLog:
	
	* gdb.texinfo (Ada Glitches): Remove paragraph describing the
	occasional case where the debugger prints an array address
	instead of the array itself.
