* vm_core.h, vm_insnhelper.h: move decl. of
ruby_vm_global_state_version and related macros
from vm_core.h to vm_insnhelper.h.
* vm.c (vm_clear_all_cache): added. This function is called
when ruby_vm_global_state_version overflows.
TODO: vm_clear_all_inline_method_cache() is only place holder.
We need to implement it ASAP.
* vm_method.c (vm_clear_global_method_cache): added.
