	* tree-ssa-operands.c (push_stmt_changes): New.
	(pop_stmt_changes): New.  Update every pass that modifies
	statements to bracket modifications with
	push_stmt_changes/pop_stmt_changes.
	(discard_stmt_changes): New.
	* tree-ssa-dom.c (stmts_to_rescan): Change to stack of
	'tree *' instead of 'tree'.  Update all users.
	* tree-flow-inline.h (zero_imm_uses_p): New.
	(symbol_mem_tag): New.  Update every function that used
	to access the annotation directly.
	(set_symbol_mem_tag): Likewise.
