LOG: [M68k] Adopt VarLenCodeEmitter for move instructions
The `move` instruction has one of the most complicate sets of variants, so
we're refactoring it first before finishing up rest of the data
instructions in a separate patch.
Note that since we're introducing more `move` variants, the codegen
actually got improved in terms of code size.
