Detailed Description
This is a concrete Recipe that models a single VPlan-level instruction.
While as any Recipe it may generate a sequence of IR instructions when executed, these instructions would always form a single-def expression as the VPInstruction is also a single def-use vertex.

◆ doesGeneratePerAllLanes()
| bool VPInstruction::doesGeneratePerAllLanes | ( | ) | const |
Returns true if this VPInstruction generates scalar values for all lanes.
Most VPInstructions generate a single value per part, either vector or scalar. VPReplicateRecipe takes care of generating multiple (scalar) values per all lanes, stemming from an original ingredient. This method identifies the (rare) cases of VPInstructions that do so as well, w/o an underlying ingredient.
