Fixed duplicated warning
As `command_rhs` is always a "value expression", `command_asgn`
does not need the same check.

Do not turn on keyword_init for Struct subclass if keyword hash is
empty
This was accidentally turned on because there was no checking for
Qundef.
Also, since only a single keyword is currently supported, simplify
the rb_get_kwargs call.

`Regexp` in `MatchData` can be `nil`
`String#sub` with a string pattern defers creating a `Regexp`
until `MatchData#regexp` creates a `Regexp` from the matched
string. `Regexp#last_match(group_name)` accessed its content
without creating the `Regexp` though. [Bug #16508]

time.c (find_time_t): fix round-to-zero bug
`find_time_t` did not work correctly for year older than the Epoch
because it used C's integer division (which rounds negative to zero).
For example, `TIme.new(1933)` returned a wrong time whose year is 1922
in Asia/Kuala_Lumpur because there is no 00:00:00 1st Jan. 1933 in the
time zone.
```
$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'
1932-12-31 00:00:00 +0700
```
This change fixes the issue by using `DIV` macro instead of `/`.
Now `Time.new(1933)` returns a time in 1933.
```
$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'
1933-01-01 00:20:00 +0720

String#b: Don't depend on dependent string
Registering a string that depend on a dependent string as fstring
can lead to use-after-free. See c06ddfe and 3f95620 for details.
The following script triggers use-after-free on trunk, 2.4.6, 2.5.5
and 2.6.3. Credits to @wanabe for using eval as a cross-version way
of registering a fstring.
```ruby
a = ('j' * 24).b.b
eval('', binding, a)
p a
4.times { GC.start }
p a
```
- string.c (str_replace_shared_without_enc): when given a
dependent string, depend on the root of the dependent
string.

Get rid of indirect sharing
* string.c (str_duplicate): share the root shared string if the

cause a dangling pointer.
[Bug #15792]
str_duplicate: Don't share with a frozen shared string
This is a follow up for 3f9562015e651735bfc2fdd14e8f6963b673e22a.
Before this commit, it was possible to create a shared string which
shares with another shared string by passing a frozen shared string
to `str_duplicate`.
Such string looks like:
```
-------- -----------------
| root | ------ owns -----> | root's buffer |
-------- -----------------
^ ^ ^
----------- | |
| shared1 | ------ references ----- |
----------- |
^ |
----------- |
| shared2 | ------ references ---------
-----------
```
This is bad news because `rb_fstring(shared2)` can make `shared1`
independent, which severs the reference from `shared1` to `root`:
```c
/* from fstr_update_callback() */
str = str_new_frozen(rb_cString, shared2); /* can return shared1 */
if (STR_SHARED_P(str)) { /* shared1 is also a shared string */
str_make_independent(str); /* no frozen check */
}
```
If `shared1` was the only reference to `root`, then `root` can be
reclaimed by the GC, leaving `shared2` in a corrupted state:
```
----------- --------------------
| shared1 | -------- owns --------> | shared1's buffer |
----------- --------------------
^
|
----------- -------------------------
| shared2 | ------ references ----> | root's buffer (freed) |
----------- -------------------------
```
Here is a reproduction script for the situation this commit fixes.
```ruby
a = ('a' * 24).strip.freeze.strip
-a
p a
4.times { GC.start }
p a
```
- string.c (str_duplicate): always share with the root string when
the original is a shared string.
- test_rb_str_dup.rb: specifically test `rb_str_dup` to make
sure it does not try to share with a shared string.

Always mark the string returned by File.realpath as tainted

passed to File.realpath, even if one of the strings is an
absolute path, due to symlinks:
```ruby
Dir.mkdir('b') unless File.directory?('b')
File.write('b/a', '') unless File.file?('b/a')
File.symlink('b', 'c') unless File.symlink?('c')
path = File.realpath('c/a'.untaint, Dir.pwd.untaint)
path # "/home/testr/ruby/b/a"
path.tainted? # should be true, as 'b' comes from file system

Don't use single byte optimization on grapheme clusters
Unicode Text Segmentation considers CRLF as a character. [Bug #15337]
add tests using Unicode test data for grapheme clusters
Add file test/ruby/enc/test_grapheme_breaks.rb to test String#each_grapheme_cluster
and \X extended grapheme cluster matcher in regular expressions against test data
provided by Unicode (ucd/auxiliary/GraphemeBreakTest.txt).
Some lines in the data file are ignored, as follows:
- Lines with a surrogate, because Ruby doesn't handle these
- The case of "\r\n", because there is a bug (#15337) in the implementation
remove guard against bug #15337, because it is fixed

parse.y: last location from bison
* parse.y (command): set the last location from the location
managed by bison, so that other nodes are not needed.

compile.c: fix peephole optimization
* compile.c (iseq_peephole_optimize): should `pop` before jump
instruction which succeeds to `newarray` of a literal object,
not after. [ruby-core:89536] [Bug #15245]

infect taint flag on Array#pack and String#unpack
with the directives "B", "b", "H" and "h".
* pack.c (pack_pack, pack_unpack_internal): infect taint flag.
* test/ruby/test_pack.rb: add test for above.

check trace flags at loading [Bug #14702]
* iseq.c (iseq_init_trace): at ISeq loading time, we need to check
`ruby_vm_event_enabled_flags` to turn on trace instructions.
Seprate this checking code from `finish_iseq_build()` and make
new function. `iseq_ibf_load()` calls this funcation after loading.
* test/ruby/test_iseq.rb: add a test for this fix.
