Before this change, we were sometimes using introductory platform version as the starting version where a symbol is considered belonging to the original binary. However, this is insufficient because backdeploying to a platform version prior to a symbol's introductory version can happen. When it happens, we should expect the moved symbol to be found in the moved-from library, not the moved-to one. Expecting the symbol to be found in the moved-to library can lead to crasher.
