The fix was based on PR from @dearblue

Fix `mrb_vformat()` crashes with `MRB_INT16`
2019-09-08Fix `mrb_vformat()` crashes with `MRB_INT16`dearblue
If `MRB_INT16` is specified, the variable length argument `mrb_int` is converted to `int`.
2019-09-07Revert part of #4225Yukihiro "Matz" Matsumoto
Since in mruby, Integer and Float interchange frequently (mostly on overflow), so adding explicit `.0` can cause problems sometimes. For example: https://github.com/mattn/mruby-json/pull/40 https://github.com/pepabo/mruby-msd/pull/13 https://github.com/mattn/mruby-json/pull/42

ref: https://github.com/mruby/mruby/pull/4483#issuecomment-498001736 In this configuration, `tt` of `RBreak::val` is set into `RBreak::flags`.
2019-08-21Prioritize embedded string over nofree (or normal) stringKOBAYASHI Shuji
Prioritize embedded string in the following functions: - `str_new_static` - `str_new` - `mrb_str_new_capa` - `mrb_str_pool` The reasons are as follows: - Consistency with `mrb_str_byte_subseq` and `str_replace`. - Memory locality increases and may be slightly faster. - No conversion cost to embedded string when modifying the string.
2019-08-20Use `RBasic` padding for embedded string on 64-bit CPUKOBAYASHI Shuji
On 64-bit CPU, there is padding in `RBasic`, so reorder the fields and use it as buffer of embedded string. This change allows 4 more bytes to be embedded on 64-bit CPU. However, an incompatibility will occur if `RString::as::ary` is accessed directly because `RString` structure has changed.

Because this field is used as capacity of string buffer.

2019-08-17Fix `String#rindex` with invalid UTF-8 stringdearblue
Previously `String#rindex` returned the wrong index when given an invalid UTF-8 string. ```terminal % ruby26 -e 'str = "\xf0☀\xf1☁\xf2☂\xf3☃\xf0☀\xf1☁\xf2☂\xf3☃"; p str.rindex("☁")' 11 % ./mruby-head -e 'str = "\xf0☀\xf1☁\xf2☂\xf3☃\xf0☀\xf1☁\xf2☂\xf3☃"; p str.rindex("☁")' nil % ./mruby-patched -e 'str = "\xf0☀\xf1☁\xf2☂\xf3☃\xf0☀\xf1☁\xf2☂\xf3☃"; p str.rindex("☁")' 11 ```

2019-08-16SHARED/FSHARED string is not required when sharing NOFREE stringKOBAYASHI Shuji
I think the string buffer of NOFREE string always exists and does not need to be released, so it can be shared as another NOFREE string. Also changed the `mrb_shared_string` field order so that eliminate padding if `int` and `mrb_int` sizes are less than pointer size.
2019-08-16Avoid creating unnecessary empty arrays on splat.Yukihiro "Matz" Matsumoto
But this changes requires `OP_ARYCAT` and `OP_ARYPUSH` to accept `nil` as their first operand. Alternative VMs (e.g. `mruby/c`) that understand mruby bytecode need to be updated.
2019-08-16Stop raising exceptions from `undef` C API.Yukihiro "Matz" Matsumoto
Some `undef' functions may be called before initialization, thus causes infinite error recursion.

2019-08-11`mrb_str_modify_keep_ascii` can embed one more byteKOBAYASHI Shuji
The condition to make an embedded string was incorrect. Because there were several similar codes, extracted into `RSTR_EMBEDDABLE_P` macro.
