    c++: throwing dtor and empty try [PR113088]

    maybe_splice_retval_cleanup assumed that the function body can't be emp=
ty
if
    there's a throwing cleanup, but when I added cleanups to try blocks in
    r12-6333-gb10e031458d541 I didn't adjust that assumption.

            PR c++/113088
            PR c++/33799

    gcc/cp/ChangeLog:

            * except.cc (maybe_splice_retval_cleanup): Handle an empty bloc=
k.

    gcc/testsuite/ChangeLog:

            * g++.dg/eh/return2.C: New test.
