mem: Explicitly specify the endianness in the abstract memory.
The accessors are used for debugging output. If we're using an ISA where there's an endianness, we use that explicitly, falling back to a binary dump if the size isn't supported. If not, then we just dump the data without interpretation regardless of size.
