[s390, Committed] Use INTVAL only on CONST_INT in addptrdi3 and addptrsi3

[Tom de Vries]

Andreas,

This patch ensures that INTVAL is only used on a CONST_INT in define_expands 
addptrdi3 and addptrsi3. I ran into this issue when building gcc for target s390 
with --enable-checking=yes,rtl.

Finished s390 build with patch, and committed as trivial.

Thanks,
