mir: Reinstate while loop in deaggregator pass A previous commit must have removed the `while let` loop here by mistake; for each basic block, it should find and deaggregate multiple statements in their index order, and the `curr` index tracks the progress through the block. This fixes both the case of deaggregating statements in separate basic blocks (preserving `curr` could prevent that) as well as multiple times in the same block (missing loop prevented that). 2016-12-09 09:28:54 -06:00			`// Test that deaggregate fires more than once per block`
