The #4520 tried to address the issue, but it changes the type of
`mrb_check_frozen` argument; close #4520

Reverses UTF-8 strings without allocated heap for working memory.
1. String before reversing:
```
"!yburmの界世"
# byte unit
[33, 121, 98, 117, 114, 109, 227, 129, 174, 231, 149, 140, 228, 184, 150]
```
2. Reverse the byte order of each character:
```
[33, 121, 98, 117, 114, 109, 174, 129, 227, 140, 149, 231, 150, 184, 228]
```
3. Reverse the whole byte order and complete:
```
[228, 184, 150, 231, 149, 140, 227, 129, 174, 109, 114, 117, 98, 121, 33]
# string

Make non-paragraph mode twice as fast. Performance is within a factor of 2
of the original implementation.

mruby/mruby#4511 demonstrated an infinite loop in `String#each_line` when
given an empty string separator. In MRI, an empty separator places
String#each_line in paragraph mode, where the String is separated on
successive runs of newlines. In paragraph mode, the String
`"abc\n\n\ndef\nxyz"` is split into `["abc\n\n\n", "def\nxyz"]`.
This commit makes the String#each_line implementation as close to
ruby/spec compliant as possible given the limitations of mruby core.
With this patch, the following specs fail for `String#each_line`:
- uses `$/` as the separator when none is given (can be fixed by
aliasing and redefining the method to use $/ as the default value
of separator in mruby-io)
- when no block is given returned Enumerator size should return nil
(`Enumerator#size` is not supported on mruby)
- tries to convert the separator to a string using to_str (`String#to_str`
is not implemented on mruby)
This patch has similar memory consumption compared to the prior
implementation and is takes 4x the time the prior implementation takes to
execute:
```console
/usr/bin/time -l ./bin/mruby -e '("aaa\n\nbbbbb\n\n\n\n\ncccc" * 100000).each_line("\n") { }';
```

Previous example doesn't work because string key (frozen) can't be modified.
|
|
For example on 32 bit mode, when `p = 0xfffffffd`, `e = 0xfffffffe`
and `len = 4`, the sum of `p` and `len` can be to `1`, and comparison
with `e` will to be false.
As a result, a segmentation fault occurs by referring to address 0.

CRuby supports a 'o' `Regexp` option for `Regexp` literals, e.g. `/foo/o` that disables multiple interpolation passes.
This commit adds support for parsing such literals. Nothing is done with the option, it is consumed and ignored by the parser.

`mrb_class_path()` always returns a new string or `nil`.

Adjust allocation size in `mrb_id_attrset()` (`mruby-struct`)

Before this patch:
$ bin/mruby -e 'Struct.new(:a,:b).new[-3]'
#=> offset -1 too small for struct(size:2) (IndexError)
After this patch (same as Ruby):
$ bin/mruby -e 'Struct.new(:a,:b).new[-3]'
#=> offset -3 too small for struct(size:2) (IndexError)
