S/390: Disallow SImode in s390_decompose_address

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.

gcc/ChangeLog:

2016-03-01  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* config/s390/s390.c (s390_decompose_address): Don't accept SImode
	anymore.
