* 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.
