cp-tree.def (SCOPE_STMT): Take one operand.

	* cp-tree.def (SCOPE_STMT): Take one operand.
	* cp-tree.h (SCOPE_STMT_BLOCK): New macro.
	(SCOPE_NULLIFIED_P): Redefine.
	(SCOPE_NO_CLEANUPS_P): New macro.
	(add_scope_stmt): Change prototype.
	* decl.c (poplevel): Tidy.  Warn about unused variables here.
	Record SCOPE_STMT_BLOCKs.
	(finish_function): Keep DECL_INITIAL for functions that might be
	inlined.
	* ir.texi: Document SCOPE_NO_CLEANUPS_P.
	* semantics.c: Include rtl.h.
	(add_scope_stmt): Return the new scope statement and, for an
	end-of-scope statement, its matching begin statement.  Don't set
	SCOPE_NULLIFIED_P.
	(do_pushlevel): Simplify, now that we are always
	function-at-a-time.
	(do_poplevel): Likewise.  Record SCOPE_STMT_BLOCKs.
	(expand_stmt): Don't call expand_start_bindings or
	expand_end_bindings for a scope with SCOPE_NO_CLEANUPS_P set.
	* tree.c (copy_tree_r): Clear SCOPE_STMT_BLOCK rather than setting
	SCOPE_NULLIFIED_P.
	* Makefile.in (semantics.o): Depend on RTL_H.
