These are bookend passes designed to help preserve line information across passes which delete, move and clone instructions. The propagation pass attaches a debug line instruction to every instruction based on SPIR-V line propagation rules. It should be performed before optimization. The redundant line elimination pass eliminates all line instructions which match the previous line instruction. This pass should be performed at the end of optimization to reduce physical SPIR-V file size. Fixes #2027.
