We added a hash-based cache check in DRT_TypeCheck until the
SubtypeNTestCache stubs handle hash-based caches to avoid doing
the full runtime check when unnecessary, but did not do so for
DRT_InstanceOf. This fixes that until an upcoming CL that adds
support for hash-based caches in the SubtypeNTestCacheStubs lands.
TEST=Manual inspection of profiles before and after change. Not
adding an automated test as this change is a temporary bandaid
similar to the tested path in DRT_TypeCheck that will be removed soon.
