Ayal Zaks 303a302e55 [LV] Fix PR34523 - avoid generating redundant selects ... When converting a PHI into a series of 'select' instructions to combine the incoming values together according their edge masks, initialize the first value to the incoming value In0 of the first predecessor, instead of generating a redundant assignment 'select(Cond[0], In0, In0)'. The latter fails when the Cond[0] mask is null, representing a full mask, which can happen only when there's a single incoming value. No functional changes intended nor expected other than surviving null Cond[0]'s. This fix follows D35725, which introduced using null to represent full masks.
