This test was added because of a bug in verifier.c:sync_linked_regs(), upon range propagation it destroyed subreg_def marks for registers. The test is written in a way to return an upper half of a register that is affected by range propagation and must have it's subreg_def preserved. This gives a return value of 0 and leads to undefined return value if subreg_def mark is not preserved.
