Log:
[coro] Remove unused yield logic labels.

We build a CFG in the front end with the 'special scope-exiting
return' hidden from the cleanups machinery.  Once the CFG is re-
written, these labels are redundant - however, they can confuse
BB merges when EH labels are also present.  Remove the unused
labels for now.
