    [PR104961] LRA: split hard reg for reload pseudo with clobber.

    Splitting hard register live range did not work for subreg of a
    multi-reg reload pseudo.  Reload insns for such pseudo contain clobber
    of the pseudo and splitting did not take this into account.  The patch
    fixes it.

            * lra-assigns.cc (find_reload_regno_insns): Process reload pseudo
clobber.
