KOBAYASHI Shuji be78b5d8f7 Fix RBreak exceeding 6 words on 32-bit mode w/o boxing and MRB_USE_FLOAT 
ref: https://github.com/mruby/mruby/pull/4483#issuecomment-498001736

In this configuration, `tt` of `RBreak::val` is set into `RBreak::flags`.

Yukihiro "Matz" Matsumoto 4c001673b6 Avoid C++ strict aliasing warning. 
Based on code proposed by @dearblue to avoid the warning:
`dereferencing type-punned pointer will break strict-aliasing rules`.

KOBAYASHI Shuji 8157672a29 Use RBasic padding for embedded string on 64-bit CPU 
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.

Ryan Lopopolo b5662c87c8 Allow external definition of MRB_API macro 
When building WebAssembly targets with clang (e.g. wasm32-unknown-unknown), all
symbols are hidden by default. To export a symbol, it must be marked with

    __attribute__((visibility(default)))

Rather than detecting this exotic target in mruby, allow MRB_API to be defined
externally.

KOBAYASHI Shuji 450684ab33 mrb_str_modify_keep_ascii can embed one more byte 
The condition to make an embedded string was incorrect. Because there were
several similar codes, extracted into `RSTR_EMBEDDABLE_P` macro.

Yukihiro "Matz" Matsumoto 6f67fddb87 Fix FIXABLE_FLOAT() on MRB_INT64; ref #4566 
Normal `TYPED_FIXABLE(f,mrb_float)` does not work on 64bit int from
casting problems. The new approach works well, but assumes two's
complement and IEEE-754 floating point numbers.

Yukihiro "Matz" Matsumoto 991bdd4ed7 Rename MRB_STR_NO_UTF to 'MRB_STR_ASCII`; close #4550 
In #4550, @shuuji proposed the name name `MRB_STR_NO_MULTI_BYTE` for
more precise description. Although I agree that the name name is
correct, but the flag means the string does not contain multi byte UTF-8
characters, i.e. all characters fit in the range of ASCII.

Yukihiro "Matz" Matsumoto e941cf06a3 Export mrb_int_value that converts mrb_float to Fixnum. 
Or `Float` if `mrb_float` value is too big (or too small) to fit in
`mrb_int`. The `_int_` in `mrb_int_value` means `Integral` module, which
represents integer-like values in mruby.

an exception after the length check.
