Andreas Haas 72d5f3848e Terminate the decoding loop more gracefully. 
The decoder has the assumption that it always holds that pc <= end.
However, in the FunctionBodyDecoder, end was set to start to terminate
the decoding loop. Thereby the assumption was violated, which caused a
crash. I set end to pc now to end the decoding loop, which preserves
the assumption and terminates the loop.
