re PR debug/43084 (ICE -fipa-struct-reorg -g (VTA)) 

PR debug/43084
	* ipa-struct-reorg.c (add_access_to_acc_sites): For debug stmts don't
	populate vars array.
	(create_new_general_access): For debug stmts just reset value.
	(get_stmt_accesses): For accesses within debug stmts just record them
	using add_access_to_acc_sites instead of preventing the peeling or
	counting them as accesses.

	* gcc.dg/pr43084.c: New test.
