Partially allow overriding of `String#[]` methods

Fix typo for `OP_SETIDX`

This is for the purpose of supporting `Regexp`.

- configuration and build

  ```console
  % cat regexp_config.rb
  MRuby::Lockfile.disable
  MRuby::Build.new do
    toolchain "clang"
    enable_debug
    gem core: "mruby-bin-mruby"
    gem core: "mruby-print"
    gem mgem: "mruby-onig-regexp"
    #gem mgem: "mruby-regexp-pcre"
  end

  % rake MRUBY_CONFIG=regexp_config.rb
  ```

- mruby HEAD (bec074e6)

  ```console
  % build/host/bin/mruby -e 'p "abcdefg"[/.(?=...$)/]'
  -e:1: can't convert OnigRegexp into Integer (TypeError)
  ```

- with this patch

  ```console
  % build/host/bin/mruby -e 'p "abcdefg"[/.(?=...$)/]'
  "d"
  ```

Existing call stack depth checks are unified into this check in
`cipush()`. The maximum depth is now specified by `MRB_CALL_LEVEL_MAX`
(the default is 512).  The older `MRB_FUNCALL_DEPTH_MAX` is no longer
used.

When the length operand is zero, we don't need `OP_MOVE` but adjust the
destination operand instead.

Which represent `obj[int]` and `obj[int]=val` respectively where `obj`
is either `string`, `array` or `hash`, so that index access could be
faster. When `obj` is not assumed type or `R(a+1)` is not integer, the
instructions fallback to method calls.

Merge branch 'inline-struct-gem' of https://github.com/dearblue/mruby into dearblue-inline-struct-gem

- `mruby-binding-core` should be handle through dependency
- `mruby-inline-struct` is only for tests

It used to be compiled to the static string in the compiler. But the
encoding status actually depends on the runtime configuration. A new
method `Kernel#__ENCODING__` is introduced to implement the feature.

Otherwise, the following code will crash:

```ruby
1.times{{}until 1; break}
```

Rename `MRB_WORDBOX_USE_HEAP_FLOAT` to `MRB_WORDBOX_NO_FLOAT_TRUNCATE'.

This reverts commit 913a0a5a.
In some cases, `OP_HASHADD` operand may not be `Hash`. We should check
explicitly in those cases.

In addition, add `NODE_SYM` for always true expression.

The invocation of `initialize` hook can cause infinite recursion too
easily. We stop invoking the method for safety, at the cost of less
flexibility.

The `initialize` methods (e.g. ones defined in `mrblib/10error.rb`) are
called only from `NoMethodError.new(args..)` forms.
