[PATCH] LiveRangeCalc: Don't start liveranges of PHI instruction at the block begin.

[Quentin Colombet]

Hi Matthias,

I am not sure this is the right thing to do.
Because of this change, we would have an order in phi definitions whereas there is in fact none.

That may make the machine verifier code more complicated, but I think this is what need to be fixed.

What do you think?

Thanks,
-Quentin
