After Y is never used anymore with SImode operands we can finally
disallow SImode (if != Pmode) in s390_decompose_address. In fact that
was the whole point of the patch series.

2016-01-14 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.c (s390_decompose_address): Don't accept SImode
anymore.
