Need to mark fibers referenced from env; fix #3837
...
The issue #3837 is a regression of #3819 . I was mistakenly removed
a important code to mark fibers from `env`.

Heavily refactored how lexical scope links are implemented; fix #3821
...
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`.

Add new type of shared string: RSTR_FSHARED.
...
`RSTR_FSHARED` use frozen strings as shared body instead of
`struct mrb_shared_string`. This reduces allocation from
literal strings.

Restructure irep->outer chain; fix #3804
...
Instead of `irep -> proc` chain, we use `irep -> irep` chain to
avoid GC bugs like #3804 . We added `target_class` reference to
`mrb_irep` struct. That means one more word consumption per `irep`.

Embed small size array elements in the heap.
...
It reduces the memory consumption and sometimes improve the
performance as well. For example, the consumed memory size
of `bench/bm_ao_render.rb` is reduced from 1.2GB to 1GB, and
its total execution time become 18.795 sec from 22.229 sec.
