    Fix segfault during delay slot scheduling pass

    This is a small regression present on the mainline and 13 branch, altho=
ugh
    the underlying problem has probably been there for ages, in the form of=
 a
    segfault during the delay slot scheduling pass, for a function that fal=
ls
    through to exit without any instruction generated for the end of functi=
on.

    gcc/
            PR rtl-optimization/113140
            * reorg.cc (fill_slots_from_thread): If we are to branch after =
the
            last instruction of the function, create an end label.

    gcc/testsuite/
            * g++.dg/opt/delay-slot-2.C: New test.=
