Serguei Katkov a54df3d63c [SimpleLoopUnswitch] Add a test case exposing a bug 
This test exposes a bug in SimpleLoopUnswitch that leads to a crash on
assert(SuccessorsCount > 1 && "Cannot unswitch a condition without multiple distinct successors!");
when SimpleLoopUnswitch considers unswitching of a loop by a switch with one successor.

Fix will be submitted soon.
