* Refactoring: replace "Destination" and the ownership qualifier by a single "Mode". This represents much better the mode how the instruction is to be lowered. NFC * Make assign_by_wrapper printable and parseable. * Fix lowering of the assign modes for indirect results of the init-closure: The indirect result was initialized and not assigned to. The fix is to insert a destroy_addr before calling the init closure. This fixes a memory lifetime error and/or a memory leak. Found by inspection. * Fix an iterator-invalidation crash in RawSILInstLowering * Add tests for lowering assign_by_wrapper.
