Read the comments regarding SwsAArch64OpImplParams in ops_impl.h for more information.

Most SwsOp work on fields described by SWS_OP_NEEDED(). The few that don't will override this field later.

The different types of read operations have been split into their own SwsUOpType to simplify the implementation.

The different types of write operations have been split into their own SwsUOpType to simplify the implementation.

Detect whether copies are needed or if a simple permute is enough.
