CodeGen: BlockPlacement: Adjust test case so it covers rL297925. NFC

I had ajusted the test case before when testing a chain of length 2, and then
reverted it with rL296845 when I switched to 3 triangles. After running
benchmarks and examining generated code at length 2 I forgot to put the test
back.
