84d83482c8 UNALIGNED_MEMBER_ACCESS only for clang
* eval_intern.h (UNALIGNED_MEMBER_ACCESS): enable only on clang.
  gcc does not complain about pointers to member of unaligned
  struct.

2108e55c0b use "enum ruby_tag_type" and TAG_NONE.
Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.

Some code used "status" instead of "state". To make them clear,
rename them to state.

We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

9d09240d9e rb_execution_context_t: move stack, stack_size and cfp from rb_thread_t
The goal is to reduce rb_context_t and rb_fiber_t size
by removing the need to store the entire rb_thread_t in
there.

[ruby-core:81045] Work-in-progress: soon, we will move more fields here.

9f60791a04 * vm_core.h: revisit the structure of frame, block and env.
[Bug #12628]

  This patch introduce many changes.

  * Introduce concept of "Block Handler (BH)" to represent
    passed blocks.

  * move rb_control_frame_t::flag to ep[0] (as a special local
    variable). This flags represents not only frame type, but also
    env flags such as escaped.

  * rename `rb_block_t` to `struct rb_block`.

  * Make Proc, Binding and RubyVM::Env objects wb-protected.

  Check [Bug #12628] for more details.

18bbd05709 * method.h: split rb_method_definition_t::flag to several flags.
`flag' contains several categories of attributes and it makes us
  confusion (at least, I had confused).
  * rb_method_visibility_t (flags::visi)
    * NOEX_UNDEF     -> METHOD_VISI_UNDEF     = 0
    * NOEX_PUBLIC    -> METHOD_VISI_PUBLIC    = 1
    * NOEX_PRIVATE   -> METHOD_VISI_PRIVATE   = 2
    * NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
  * NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
  * NOEX_BASIC       -> basic (flags::basic, 1 bit)
  * NOEX_MODFUNC     -> rb_scope_visibility_t in CREF
  * NOEX_SUPER       -> MISSING_SUPER (enum missing_reason)
  * NOEX_VCALL       -> MISSING_VCALL (enum missing_reason)
  * NOEX_RESPONDS    -> BOUND_RESPONDS (macro)
  Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
  Background:
    I did not know what "NOEX" stands for.
    I asked Matz (who made this name) and his answer was "Nothing".
    "At first, it meant NO EXport (private), but the original
    meaning was gone."
    This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
  method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
  scope visibility.
  It has 3 method visibilities (public/private/protected)
  and `module_function`.

* eval_intern.h (TH_PUSH_TAG, TH_EXEC_TAG): refine stack overflow
  detection.  chain local tag after setjmp() successed on it, because
  calling setjmp() also can overflow the stack.

  TH_EXEC_TAG().

1c0323adbc Fix build when gcc is used and the platform's libc lacks alloca().
* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c
  (alloca): Make alloca() globally available by moving the
  ultimate ifdef's to ruby/ruby.h.  Gcc hides its builtin alloca()
  when compiling with -ansi, and linking thus fails on platforms
  that lack their own alloca() implementation in libc, which
  include OpenBSD and some ports of NetBSD.  We use alloca()
  everywhere including from within third party C extentions, so
  alloca() must be made globally available. [Bug #7307]

* addr2line.c (alloca): Replace the alloca() part with the
  ultimate ifdef's. [Bug #7307]
