Replace complex `count_returns` method with a ProgramVisitor.
These ProgramVisitor classes do the exact same work as count_returns.
Hopefully they are easier for us to reason about, since we no longer
have one omni-method trying to implement three different counts at once.
count_returns still exists in this CL so we can SkASSERT that our
results are unchanged. It is removed entirely in the followup CL.
