Detailed Description
A recipe for widened phis.
Incoming values are operands of the recipe and their operand index corresponds to the incoming predecessor block. If the recipe is placed in an entry block to a (non-replicate) region, it must have exactly 2 incoming values, the first from the predecessor of the region and the second from the exiting block of the region.
