[lworld] RFR: 8314190: [lworld] Missing InlineTypeNode re-materialization during type sharpening. [v3]

[Jatin Bhateja]

> -  Currently we try to sharpen the object type to a narrower type to optimize object type comparison against a class constant.
>  - This is achieved by inserting a CheckCastPP node which casts the object type to a higher speculative type, if cast type is an inlinetype we need to rematerialize InlineTypeNode from newly casted object which was missing and is fixed by the patch.
> 
> Kindly review.
> 
> Tier1 regressions are clean.
