RFR(XS) 8024917: Remove public pointer to PhaseLive in PhaseChaitin

[Niclas Adlertz]

Hi all,

Removing a public pointer to PhaseLive which can be accessed at any time from PhaseChaitin, instead passing a reference of the PhaseLive instance to the methods that use it.

A review would be much appreciated.
