2017-11-03Always check division-by-zero to avoid undefined behavior; fix #3816Yukihiro "Matz" Matsumoto
Also removed the code to normalize NaN value for `MRB_NAN_BOXING`. Tha code was added to fix #1712 but no longer required after 249f05e7d.

2017-10-29Need to check number of argument of `Struct#new`; fix #3823Yukihiro "Matz" Matsumoto
2017-10-28Fixed UPVAR gotchas; fix #3835Yukihiro "Matz" Matsumoto
Both `uvenv` function and `env` generation in `create_proc_from_string` function have bugs to handling enclosed environment objects.
2017-10-28Heavily refactored how lexical scope links are implemented; fix #3821Yukihiro "Matz" Matsumoto
Instead of `irep` links, we added a `upper` link to `struct RProc`. To make a space for the `upper` link, we moved `target_class` reference. If a `Proc` does not have `env`, `target_class` is saved in an `union` shared with `env` (if a `Proc` has env, you can tell it by `MRB_PROC_ENV_P()). Otherwise `target_class` is referenced from `env->c`. We removed links in `env` as well. This change removes 2 members from `mrb_irep` struct, thus saving 2 words per method/proc/block. This also fixes potential memory leaks due to the circular references caused by a link from `mrb_irep`.
