Remove inadvertent symbol creation from send, __send__, and public_send
When I was first working on the inadvertent symbol creation removal code, I didn't think it was possible to handle send because method_missing requires a symbol as the first argument. But once I figured out how to handle the similar situation in respond_to? for respond_to_missing? (and used the same technique with const_get for const_missing), the same idea works for the send methods. Basically, if method_missing has been overridden, you must create the symbol, but if not, you can just raise a NoMethodError without creating the symbol.
I didn't add a test for it since I saw the tests for const_get and respond_to? were commented out in r32710 and r32711.

Jeremy, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
- vm_eval.c (make_no_method_execption): extract from raise_method_missing().
- vm_eval.c (send_internal): remove inadvertent symbol creation from public_send. based on a patch by Jeremy Evans in [ruby-core:38576]. [Feature #5112]
- vm_insnhelper.c (vm_call_method): remove inadvertent symbol creation from send and send, too.
