* 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.
