c++: -Wdangling-reference and lambda false warning [PR109640]
-Wdangling-reference checks if a function receives a temporary as its
argument, and only warns if any of the arguments was a temporary. But
we should not warn when the temporary represents a lambda or we generate
false positives as in the attached testcases.
