This broke building gcc with C++14 system compilers.
../../gcc/auto-profile.cc: In member function ‘std::pair<const char*, int> autofdo::string_table::get_original_name(const char*) const’:
../../gcc/auto-profile.cc:1129:7: warning: init-statement in selection statements only available with ‘-std=c++17’ or ‘-std=gnu++17’ [-Wc++17-extensions]
 1129 |   if (symtab_node *n
      |       ^~~~~~~~~~~
This is valid only in C++17 and later.

Fixed thusly.

	* auto-profile.cc (string_table::get_original_name): Avoid using
	init-statement in selection statement.
