Only assert ractor_shareable is consistent on ivar_set for T_OBJECT
Before d594a5a8bd0756f65c078fcf5ce0098250cba141, we were only
asserting that the value on an ivar_get was ractor_sharable if the
object was a T_OBJECT and also ractor shareable. We should still
be doing this check only if the object is a T_OBJECT and ractor
shareable
