With x86_64 as host, we do not have any temporaries with which to
resolve cycles, but we do have xchg. As a side bonus, the set of
graphs that can be made with 3 nodes and all nodes conflicting is
small: two. We can solve the cycle with a single temp.
This is required for x86_64 to handle stores of i128: 1 address
register and 2 data registers.
