Separate jump destination check in `OP_R_RETURN`.
In the past code, the current `callinfo (ci)` was modified, thus it was
possible to pop `ci` beyond the `cibase`, that could cause out of memory
bound access for the code like the following:
```ruby
def m2
lambda {
Proc.new {
return :return # return from the method
}
}.call.call
:never_reached
end
p m2
```
