These are generated by the Java compiler javac depending on the 
structure of the cases. I believe that if you write a switch statement 
with contiguous values, then javac will generate a LookupSwitch bytecode 
instruction, while a range of values will generate a TableSwitch 
bytecode instruction. In either case, Soot just converts the bytecode 
into Jimple directly.
