compiler: implement copy directly
The compiler now implements the copy builtin directly instead of calling sliceCopy. The length is calculated with the llvm.umax.* intrinsics, and the move is performed by llvm.memmove.*. Both of these operations are easily understood by LLVM's optimization passes. The type's alignment is also provided to llvm.memmove.*, which is useful when rewriting the move. Interp no longer needs to reimplement sliceCopy. Some edge case handling was implemented by sliceCopy but not llvm.memmove.*/llvm.memcpy.*. I copied this over, so copies of external slices should work now. Volatile moves/copies are now run at runtime by interp. There is a 4-byte size increase due to some confusing length logic in sendUSBPacket. I will look at sendUSBPacket in a future PR.
