s390: Fix expander popcountv8hi2_vx
The normal form of a CONST_INT which represents an integer of a mode
with fewer bits than in HOST_WIDE_INT is sign extended. This even holds
for unsigned integers.
This fixes an ICE during cse1 where we bail out at rtl.h:2297 since
INTVAL (x.first) == sext_hwi (INTVAL (x.first), precision) does not hold.
gcc/ChangeLog:
* config/s390/vector.md (popcountv8hi2_vx): Sign extend each
unsigned vector element.
