Summary: Letting them begin at the PHI instruction slightly simplifies the code but more importantly avoids breaking the assumption that live ranges starting at the block begin are also live at the end of the predecessor blocks. The MachineVerifier checks that but was apparently never run in the few instances where liveranges are calculated for machine-SSA functions.
