if (_8 != _14)
goto <bb 3>;
else
goto <bb 6>;
<bb 3>:
target_bb.1_15 = target_bb;
if (_14 == target_bb.1_15)
goto <bb 4>;
else
goto <bb 6>;
<bb 4>:
if (_8 != target_bb.1_15)
goto <bb 5>;
else
goto <bb 6>;
Presumably depending on the ordering in the conditionals, we should discover
that in bb4 _8 and _15 are equal and eliminate the test.
