qemu-s390x puts a wrong value into SIGILL's siginfo_t's psw.addr: it
should be a pointer to the instruction following the illegal

Patch 1 fixes the issue, patch 2 adds a test.
v1: https://lists.nongnu.org/archive/html/qemu-devel/2021-05/msg06592.html
v1 -> v2: Use a better buglink (Cornelia), simplify the inline asm
magic in the test and add an explanation (David).
v2: https://lists.nongnu.org/archive/html/qemu-devel/2021-05/msg06649.html
v2 -> v3: Fix SIGSEGV handling (found when trying to run valgrind under
qemu-user).
There might still be something wrong:

At least it smells like some more signal (mis)handling.
