IPA-CP: Always access param_ipcp_unit_growth through opt_for_fn
2020-01-10 Martin Jambor <mjambor@suse.cz>
* params.opt (param_ipcp_unit_growth): Mark as Optimization.
* ipa-cp.c (max_new_size): Removed.
(orig_overall_size): New variable.
(get_max_overall_size): New function.
(estimate_local_effects): Use it. Adjust dump.
(decide_about_value): Likewise.
(ipcp_propagate_stage): Do not calculate max_new_size, just store
orig_overall_size. Adjust dump.
(ipa_cp_c_finalize): Clear orig_overall_size instead of max_new_size.
