decl.c (gnat_to_gnu_type, [...]): Wrap modular packed array types in both little- and big-endian cases.

2004-09-21  Robert Dewar  <dewar@gnat.com>

	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
	packed array types in both little- and big-endian cases. This change
	ensures that we no longer count on the unused bits being initialized
	for such types (and in particular ensures that equality testing will
	only read the relevant bits).
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
	These changes mean that we no longer need to initialize small packed
	arrays.
	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
	optimization to an LJM field as to its parent field.

	* ada-tree.h:, trans.c, utils.c, utils2.c:
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
