* insns.def : support direct method dispatch with "send" or "funcall".

This means that "obj.send :m" skips "BasicObject#send" invocation
(method frame creation, etc) and "obj.m" invokes directly.
If you make backtrace, there are no enties of "send" method.
* compile.c (iseq_specialized_instruction) : fix to support above
* eval.c : ditto (remove "static" from rb_f_send and rb_f_funcall
* yarvcore.c : ditto (add a external IDs for compiler)
* yarvcore.h : ditto (add a VM_CALL_SEND_BIT macro)
* yarvtest/test_method.rb : add tests for above changes
* eval.c : remove unused "Kernel#send" declaration
