/**
 * This tests that we produce valid code when having normal-flow with exceptional edges in blocks.
 * We might perform optimizations that add operations (dup, swap, etc.) before and after
 * instructions that lie on the boundary of the exception table that is generated for a basic block.
 * If live-ranges are minimized this could produce VerifyErrors. TODO(b/119771771) Will fail if
 * shorten live ranges without shorten exception table range.
