target/s390x: Fix R[NOX]SBG with T=1

|
v1: https://lists.gnu.org/archive/html/qemu-devel/2023-03/msg04493.html v1 -> v2: Work around a clang issue (Thomas). Add cc=0 test, use more human-friendly constants. Hi, This series fixes ROTATE THEN <do something with> SELECTED BITS when test-results control is on. The problem is the incorrect translation, which confuses the register allocator. Patch 1 is the fix, patch 2 adds a test.
