[PATCH 1/3] ipa-strub: Replace cgraph_node order with uid.

[Michal Jires]

ipa_strub_set_mode_for_new_functions uses node order as unique ever
increasing identifier. This is better satisfied with uid.
Order loses uniqueness with following patches.

gcc/ChangeLog:
        * ipa-strub.cc (ipa_strub_set_mode_for_new_functions): Replace
          order with uid.
        (pass_ipa_strub_mode::execute): Likewise.
