Attached patch PatchSplinter Review
If a type barrier has type "object" (but not "any object") we have to use MTypeBarrier instead of MUnbox because we have to test the object types. This patch adds an infallible unbox after the type barrier to avoid a bunch of fallible unbox instructions inside a hot loop on SS-fannkuch.
