* 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]

ultimate ifdef's. [Bug #7307]

vm->loaded_features_snapshot.

This API is not mature to become an offical API.

64bit CPU environment (sizeof(double) == sizeof(VALUE)).
flonum technique enables to avoid double object creation
if the double value d is in range about between
1.72723e-77 < |d| <= 1.15792e+77 or 0.0.
flonum Float value is immediate and their lowest two bits
are b10.
If flonum is activated, then USE_FLONUM macro is 1.
I'll write detailed in this technique on
https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/Flonum_tech
* benchmark/bmx_temp.rb: add an benchmark for simple
Float calculation.
* gc.c (id2ref, rb_obj_id): add flonum Float support.
* include/ruby/intern.h: move decl of rb_float_new(double)
to include/ruby/ruby.h.
* insns.def, vm.c, vm_insnhelper.c: add flonum optimization
and simplify source code.
* vm_insnhelper.h (FLONUM_2_P): added.

(1) add rb_hook_list_t data structure which includes
hooks, events (flag) and `need_clean' flag.
If the last flag is true, then clean the hooks list.
In other words, deleted hooks are contained by `hooks'.
Cleanup process should run before traversing the list.
(2) Change check mechanism
See EXEC_EVENT_HOOK() in vm_core.h.
(3) Add `raw' hooks APIs
Normal hooks are guarded from exception by rb_protect().
However, this protection is overhead for too simple
functions which never cause exceptions. `raw' hooks
are executed without protection and faster.
Now, we only provide registration APIs. All `raw'
hooks are kicked under protection (same as normal hooks).
* include/ruby/ruby.h: remove internal data definition and
macros.
* internal.h (ruby_suppress_tracing), vm_trace.c: rename
ruby_suppress_tracing() to rb_suppress_tracing()
and remove unused function parameter.
* parse.y: fix to use renamed rb_suppress_tracing().
* thread.c (thread_create_core): no need to set RUBY_VM_VM.
* vm.c (mark_event_hooks): move definition to vm_trace.c.
* vm.c (ruby_vm_event_flags): add a global variable.
This global variable represents all of Threads and VM's
event masks (T1#events | T2#events | ... | VM#events).
You can check the possibility kick trace func or not
with ruby_vm_event_flags.
ruby_vm_event_flags is maintained by vm_trace.c.
* cont.c (fiber_switch, rb_cont_call): restore tracing status.

NUM2LONG, and cast to unsigned long explicitly for the platforms
where SIZEOF_VALUE is larger than SIZEOF_LONG.
