Remove `Box<[Target]>` from `Instruction` (#141)
This also allows `Instruction` to be `Copy`, which massively speeds up `<Instructions as Clone>::clone` since it can now just `memcpy` the bytes using SIMD instead of having to switch on every single element. I haven't looked at the disassembly of `InstructionIter::next` yet, it could be that there are even more improvements yet to be gained from either: * Only doing work on `BrTable` (this might already be the case depending on the whims of the optimiser) * Using `unsafe` to make it a noop (we really don't want to do this, obviously, since it means that `Instructions` has to be immovable)
