Daniil Suchkov 706b22e3e4 [SimpleLoopUnswitch] Drop uses of instructions before block deletion ... Currently if instructions defined in a block are used in unreachable blocks and SimpleLoopUnswitch attempts deleting the block, it triggers assertion "Uses remain when a value is destroyed!". This patch fixes it by replacing all uses of instructions from BB with undefs before BB deletion.
