 // Calls into the V8 runtime are based on this very simple interface.
 // Note: To be able to return two values from some calls the code in runtime.cc
 // uses the ObjectPair which is essentially two 32-bit values stuffed into a
 // 64-bit value. With the code below we assume that all runtime calls return
 // 64 bits of result. If they don't, the r1 result register contains a bogus
 // value, which is fine because it is caller-saved.
