Bjorn Pettersson 227145924a [CodeGen] Introduce MachineBasicBlock::replacePhiUsesWith helper and use it. NFC ...

Summary:
Found a couple of places in the code where all the PHI nodes
of a MBB is updated, replacing references to one MBB by
reference to another MBB instead.

This patch simply refactors the code to use a common helper
(MachineBasicBlock::replacePhiUsesWith) for such PHI node
updates.
