* vm_insnhelper.h CI_SET_FASTPATH: introduce new macro
`CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'. `func' (ci->call) is called at the last of `send' (and `invokesuper') instruction. `CI_SET_FASTPATH' does not set `ci->call' when the method (stored in `ci->me') is `protected'. * vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'. After several checking (visibility, argc checking), the result of checking can be reused until re-definition of this method with inline method cache. Note that this optimization is now experimental. If you find any problem about it, please tell us. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
