Hi,
  As discussed at
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00997.html, this is the
one line patch which improves shrink wrapping for lo_sum.

OK?  Bootstrapped and tested on x86_64 and built and tested for
aarch64-elf with no regressions.  It fixes shrink_wrap_symbol_ref_1.c
which was failing with -mabi=ilp32.

Thanks,
Andrew

ChangeLog:
* shrink-wrap.c (move_insn_for_shrink_wrap): Allow LO_SUM also.
