v2: https://lists.gnu.org/archive/html/qemu-devel/2023-03/msg04699.html
v2 -> v3: Assert that o->out != NULL, mention the commit that exposed
          the problem (Philippe).

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.

Best regards,
Ilya
