... instead of falling back to lookupswitch
noticed (while fixing #4429) that only "perfect" consecutive fixnum cases generate a tableswitch
javac does some table/lookup space cost calc to decide, here just a simple size bound (of 32) is implemented
case 0, 10, 20, 30will generate a table-switch (filling in 'wholes' e.g. case 1: default)
case 0, 10, 50will generate a lookup-switch just like before
