ruby--ruby/vm_insnhelper.h
charliesome 7fafa8f376 * insns.def, vm.c, vm_insnhelper.c, vm_insnhelper.h, vm_method.c: split
ruby_vm_global_state_version into two separate counters - one for the
  global method state and one for the global constant state. This means
  changes to constants do not affect method caches, and changes to
  methods do not affect constant caches. In particular, this means
  inclusions of modules containing constants no longer globally
  invalidate the method cache.

* class.c, eval.c, include/ruby/intern.h, insns.def, vm.c, vm_method.c:
  rename rb_clear_cache_by_class to rb_clear_method_cache_by_class

* class.c, include/ruby/intern.h, variable.c, vm_method.c: add
  rb_clear_constant_cache

* compile.c, vm_core.h, vm_insnhelper.c: rename vmstat field in
  rb_call_info_struct to method_state

* vm_method.c: rename vmstat field in struct cache_entry to method_state
