Date: Fri, 9 Jul 2021 12:04:57 -0400

qemu-s390x signals with SIGILL on compare-and-trap instructions. This
breaks OpenJDK which expects SIGFPE in its implementation of implicit

This patch depends on [PATCH v6 0/2] target/s390x: Fix SIGILL and SIGFPE
psw.addr reporting

Based-on: 20210705210434.45824-1-iii@linux.ibm.com

v1 -> v2:
- Update to latest version of '... psw.addr reporting' patch
- Rebase to master and fix conflicts in tests/tcg/s390x/Makefile.target

v2 -> v3:
- Check for non-simulated IEEE exception DXC codes explicitly when
  getting si_codes
- Ensure si_code is set in all cases
- Improve comments
