It is not faulty optimization for nodes which don't have inputs (like constants not on sparc). As I said, it reduces LR
and may reduce need for spills. Also some applications may still regress even if few benchmarks we use are not.

It worked until Christian added constants load from table - as result constant become node with input edge (MachConstantBaseNode). So now we have to stretch either LR of ConstantBase node or LR of loadCon node.

The reason for this is we want to keep the RDPC instruction as close as possible to the constant table base address so that the offset is small and the constant load instruction can be a simple load. Otherwise we need other instructions to calculate the constant table base address.

On rare occasions this will cause the re-calculation of the liveness to fail. When phi nodes and their input are united in the end of the Chaitin::Split() method they get the same live range id.

The results vary a bit, not sure how much refworkload runs usually vary. Roland also tried running refworkload on his x64 Linux to see if he could see any major regression. Thank you for helping me with this Roland.
