    c++: suppress -Wdangling-reference for std::span [PR107532]

    std::span is a view and therefore should be treated as a reference
    wrapper class for the purposes of -Wdangling-reference.  I'm not sure
    there's a pattern that we could check for.

            PR c++/107532

    gcc/cp/ChangeLog:

            * call.cc (reference_like_class_p): Check for std::span.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Wdangling-reference10.C: New test.=
