[Bug 1569391] [NEW] s390x: popcnt (B9E1) support incomplete

[dann frazier]

Public bug reported:

[Impact]
valgrind fails w/ s390x binaries that include the popcnt instruction.

[Test Case]
sudo apt build-dep valgrind
apt source valgrind
cd valgrind-*
fakeroot make -f debian/rules build
make -C ./none/tests/s390x/ popcnt
perl tests/vg_regtest none/tests/s390x/popcnt
if [ $? -eq 0 ]; then
  echo "PASS"
else
  echo "FAIL"
fi

[Regression Risk]
Fix is localized to s390x. It is an upstream cherry-pick, so regression risk should be mitigated by upstream support.
