-; Test that by changing BlockFrequencyInfo we change the order in which
-; machine-sink looks for successor blocks. By not using BFI, both G and B
-; have the same loop depth and no instructions is sinked - B is selected but
-; can't be used as to avoid breaking a non profitable critical edge. By using
-; BFI, "mul" is sinked into the less frequent block G.
