Currently only ctor/dtor list and their priorities are supported. This PR adds support for the missing data field. Few implementation notes: - The assembly printer has a fixed form because previous `attr_dict` will sort the dict by key name, making global_dtor and global_ctor differ in the order of printed arguments. - LLVM's `ptr null` is being converted to `#llvm.zero` otherwise we'd have to create a region to use the default operation conversion from `ptr null`, which is silly given that the field only support null or a symbol.
