constify again.

Same as last commit, make some fields `const`.

include/ruby/ruby.h:
* Rasic::klass
* RArray::heap::aux::shared_root
* RRegexp::src
internal.h:
* rb_classext_struct::origin_, redefined_class
* vm_svar::cref_or_me, lastline, backref, others
* vm_throw_data::throw_obj
* vm_ifunc::data
* MEMO::v1, v2, u3::value

While modifying this patch, I found write-barrier miss on
rb_classext_struct::redefined_class.

Also vm_throw_data::throw_state is only `int` so change the type.
