Feature #14606: Change begin-else-end without rescue from warning to syntax error

~~~ ruby
begin
  p :foo
else
  p :bar
end

# => :foo
# => :bar
~~~

~~~ ruby
[1,2,3].each do
  p :foo
else
  p :bar
end

# => :foo
# => :bar
~~~

begin-else-end without rescue is useless and dangerous. (especially, do-else-end is easy to mistake)
In actually, programmer never intend to write like these.
Ruby interpreter can guard this case by syntax error.
