    Fix PR middle-end/98082

    this fixes an ICE introduced by the fix for PR middle-end/97078 where
    use_register_for_decl was changed to return true at -O0 for a parameter
    of a thunk.  It turns out that we need to do the same for a result in
    this case.

    gcc/ChangeLog:
            PR middle-end/98082
            * function.c (use_register_for_decl): Also return true for a result
            if cfun->tail_call_marked is true.

    gcc/testsuite/ChangeLog:
            * g++.dg/cpp2a/pr98082.C: New test.
