Hmm, so this encodes an address/offset in the bit pattern 0x03FFFFFC of the 32 bit instruction, while keeping the other bits intact? If the offset overflows, this will end up overflowing into the opcode bits.

Then again, looking at the existing arm64 cases, we do check it in some cases, but not necessarily all of them... So perhaps it's fine for now like this?
