[vector] CheckCastPP hinders vector box elimination

    Details

      Description

      CheckCastPP may hinder vector box elimination.

      Incremental inlining produces "CheckCastPP (VectorBox ...)" shape when a vector is returned from a method and stays if it's an upcast to Vector/XxxVector, thus blocking VectorBox from elimination.
