Asm5 jdk8 - test case for void lambdas and a KLUDGE to handle the invokedynamic

Dummy is a test case that uses a void lambda. Dummy.start(lambda) allows kilims kilim to run lambda, ie syntactic sugar that makes kilim sexier. this exposes a few bugs. the 2nd commit fixes void returns

the 3rd is a kludge that handles the invokedynamic. the callsite is hardcoded to Dummy. obviously more work is needed...
