decl.c (gnat_to_gnu_entity, [...]): Don't early expand pointer initialization values.

2005-12-05  Olivier Hainque  <hainque@adacore.com>

	* decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
	pointer initialization values. Make a SAVE_EXPR instead. Add comments
	about the use and expansion of SAVE_EXPRs in the various possible
	renaming handling cases.
	(components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
	abusing DECL_FCONTEXT.
