[imcc] fix end in methods GH #1168
This is the last fix for all afl-fuzz detected crashes.
And `end` op inside a user-defined method will exit a runloop unproperly.
The old ctx will be corrupted. Replace it with an equivalent `returncc` op,
which does set the continuation and context properly to end the current runloop.
`exit` would be an alternative, but we documented `end` to halt the interpreter,
which is fresh inside certain runloops. I documented this case as unspecified
behaviour.
It crashed before, now it returns.
