receive ports are not translated to the send ports

Description of SendPort.send() says:

If the message contains any receive ports, they are translated to the corresponding send port before being transmitted.

Actually this not happen, receive ports remain instanses of ReceivePortImpl.
Moreover, if the message is ReceivePort itself, dart_bin VM crashes.

What steps will reproduce the problem?
run co19 tests
LibTest/core/SendPort/send/SendPort/send/A02/t01
LibTest/core/SendPort/send/SendPort/send/A02/t02

What is the expected output? What do you see instead?
tests should pass

What version of the product are you using? On what operating system?
dart_bin build from svn revision 1499, Linux

Please provide any additional information below.

After discussion with Kasper we decided that the functionality of automatically translating receive ports to the corresponding send ports is incorrect. The documentation in the function is incorrect and will be changed.

Also we should be throwing an exception when code tries to send a message that has a receive port in it.

The documentation in SendPort.send has been fixed to indicate that it is not legal
to send receive ports in a message.
The co19 tests above have also been updated to reflect this.

The aspect of the VM correctly reporting error messages when illegal objects are
sent in a message will be handled as part of issue #5060.
