cse.c (fold_rtx): Instantiate CONSTANT_P_RTX to 0 when not optimizing, even if flag_gcse is true.
* cse.c (fold_rtx): Instantiate CONSTANT_P_RTX to 0 when not
optimizing, even if flag_gcse is true.
* toplev.c (rest_of_compilation): purge_builtin_constant_p
only needs to be called when "optimize > 0 && flag_gcse".
