[PATCH 0/4] Fix Fedora 38 Clang on s390x

[Ilya Leoshkevich]

Hi,

It was reported that Fedora 38 Clang does not run correctly under
qemu-s390x [1]. Comparing qemu and real s390x instruction traces has
shown that the implementations of LCBB and LOCFHR were not fully
correct.

This series fixes the issues and adds tests. I can now run Fedora 38
Clang under s390x emulation and compile "hello world" with it.

Best regards,
Ilya
