- Currently we try to sharpen the object type to a narrower type while generating IR for class comparison.

 - This is achieved by inserting a CheckCastPP node which casts the object type to a higher type, if cast type is an inlinetype we need to rematerialize InlineTypeNode from newly casted object which is missing currently.
