When we're doing, say, a `sgt` comparison on a memory address, we shouldn't make the _pointer_ be signed: the signedness is on the byte(s) we load from that address. This is a mostly-harmless bug (since pointers on x64 are 64 bits wide, so signedness / unsignedness is a no-op), except it triggered a sanity-checking `assert` in x64hirtoasm.
