This fixes a wrong code generation problem with the splitters introduced
with that patch: https://gcc.gnu.org/ml/gcc-patches/2015-07/msg01840.html

The target operand is used as temporary.  This fails if it matches the
source of the left shift which is read after writing the temporary.

Thanks to Dominik for debugging it and thanks to Richard for the fix!

Bootstrapped and regtested on s390x with-arch=z13.

Bye,

-Andreas-
