cuintp.c, [...]: Use gcc_assert and gcc_unreachable.

Browse Source 
2004-10-04  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

	* trans.c (assoc_to_constructor): Fix unused var warning if no checking.
	(gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
	Use gcc_assert and gcc_unreachable.

	* decl.c (gnat_to_gnu_entity, case object): Check and process a
	specified alignment before validating size.
	(gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
	stripped-down declaration for the type of the inner field when making
	a JM type.

	* utils.c (finish_record_type): Do not compute the size in units
	incrementally. Instead compute it once for the rep clause case.
	Use gcc_assert and gcc_unreachable.
