testcase for new instruction introduced by increased distance

In this example, the max distance between the jump table and the cases is
artificially augmented by the padding. Although each basic block is very small
and has very few chances to spread over several cache blocks.

In addition the 
extu.b  r1,r1
instruction can be avoided.
