After c7bcd431d9c4bfeb631a3599f1d628603e6351d6, this test started failing when
running with the new pass manager. One of the CHECKs in this file checks how the
vtable is loaded for a void cast, which involves taking 2 bitcasts from the pointer
to the original object. The order of these bitcasts changes under the new PM.
The order doesn't matter, so this relaxes the CHECKs.
