* loop.c (basic_induction_var): Typo NULL_RTX -> NULL.
(strength_reduce): Release the varrays from the no-bivs early exit.
* reload1.c (order_regs_for_reload): Init hard_reg_n_uses before
the loop over the registers.
* tree.c (save_tree_status): Set maybepermanent_firstobj NULL
for a new obstack.
(restore_tree_status): Check that instead when freeing the obstack.
