Fixes issue reported in: https://github.com/llvm/llvm-project/pull/94224 The recent commit above added an ilist_parent<ParentTy> option, which added a parent pointer to the ilist_node_base type for the list. The const methods for returning that parent pointer however were incorrectly implemented, returning `const ParentPtrTy`, which is equivalent to `ParentTy * const` rather than `const ParentTy *`. This patch fixes this by passing around `ParentTy` in ilist's internal logic rather than `ParentPtrTy`, removing the ability to have a `void*` parent pointer but cleanly fixing this error.
