     // Make sure that the lithium instruction has either no fixed register
     // constraints in temps or the result OR no uses that are only used at
     // start. If this invariant doesn't hold, the register allocator can decide
     // to insert a split of a range immediately before the instruction due to an
     // already allocated register needing to be used for the instruction's fixed
     // register constraint. In this case, The register allocator won't see an
     // interference between the split child and the use-at-start (it would if
     // the it was just a plain use), so it is free to move the split child into
     // the same register that is used for the use-at-start.
