A Scalar represents an immediate, primitive value existing outside of a memory::Allocation. It is in many ways like a small chunk of a Allocation, up to 8 bytes in size. Like a range of bytes in an Allocation, a Scalar can either represent the raw bytes of a simple value or a pointer into another Allocation

A pointer into an Allocation. An Allocation in the memory module has a list of relocations, but a Scalar is only large enough to contain one, so we just represent the relocation and its associated offset together as a Pointer here.
