Fix noreturn discovery.
Fix ipa-pure-const handling of noreturn flags. It is not safe to set it for
interposable symbols and we should also set it for aliases (just like we do for
other flags). This patch merely copies other flag handling and implements it
here.
gcc/ChangeLog:
2021-11-11 Jan Hubicka <hubicka@ucw.cz>
* cgraph.c (set_noreturn_flag_1): New function.
(cgraph_node::set_noreturn_flag): New member function
* cgraph.h (cgraph_node::set_noreturn_flags): Declare.
* ipa-pure-const.c (pass_local_pure_const::execute): Use it.
