c++: extend Wdangling-reference17.C [PR109642]
This patch extends g++.dg/warn/Wdangling-reference17.C with code
from PR109642. I'm not creating a new test because this one
already #includes the required headers.
PR c++/109642
gcc/testsuite/ChangeLog:
* g++.dg/warn/Wdangling-reference17.C: Additional testing.
