I moved the folding code into the ReinterpretCastOpExtractStridedMetadataFolder structure, that worked already with the expand_strided_metadata / reinterpret_cast pair. With this move, I was able to make the fold unconditionally. With this I don't need the isLayoutConstant method anymore (removed it).
