* stor-layout.c (is_pending_size, put_pending_size): New functions.

	(variable_size): Call put_pending_size.
	* tree.h (is_pending_size, put_pending_size): Add prototypes.
	* fold-const.c (extract_muldiv): If SAVE_EXPR is on the pending
	sizes list, put newly created SAVE_EXPR there as well.

	* gcc.c-torture/execute/20010209-1.c: New test.

	* config/ia64/ia64.c (last_group): Only 2 entries are needed.
	(errata_find_address_regs): load_group has only 2 entries.
	(errata_emit_nops): Likewise.  shladd is not problematic.
