Multiply / divide by power of two can be optimized using shifts.
This test case tests some edge cases of that optimization.

Limit flammenwehrfer's output length for github issues

Remove broken Ackerman.inf.java test

See merge request !50

This test is actually wrong
* It can terminate (thous is not an infinte loop)
* It will crash with properly optimized code due to a huge call stack

This test assumes that the generated code is too slow to run into stack size problems before it runs into timeout problems

Otherwise github sadly rejects the edit
