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.
* marshal.c: support flonum output.
* numeric.c (rb_float_new_in_heap): added.
* parse.y: support flonum.
* random.c: ditto.

Patch by Google Inc. [ruby-core:45073].
* configure.in (RUBY_NACL): New M4 func to configure variables for
NaCl.
(RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names
of Pepper interface types.
(BTESTRUBY): New variable to specify which ruby should be run on
"make btest". NaCl can run the built binary by sel_ldr, but it need
rbconfig.rb. So this variable is distinguished from $MINIRUBY.
* thread_pthread.c: Disabled some features on NaCl.
* io.c: ditto.
* process.c: ditto.
* signal.c: ditto.
* file.c: ditto.
* missing/flock.c: ditto.
* nacl/pepper_main.c: An example implementation of Pepper application
that embeds Ruby.
* nacl/example.html: An example of web page that uses the Pepper
application.
* nacl/nacl-config.rb: Detects variants of NaCl SDK.
* nacl/GNUmakefile.in: Makefile template for NaCl specific build
process.
* nacl/package.rb: script for packaging a NaCl-Ruby embedding
application.
* nacl/reate_nmf.rb: Wrapper script of create_nmf.py
* dln.c (dln_load): Added a hack to call on NaCl.
* util.c (ruby_getcwd): Path to the current directort is not available
on NaCl.

posix_memalign() are not defined together normally.

prevent fibers from destroy.
* gc.c (rb_objspace_call_finalizer): don't sweep fibers at finalizing
objspace.
* internal.h (rb_fiber_reset_root_local_storage, rb_obj_is_fiber):
add prototypes.
* vm.c (ruby_vm_destruct): reset main thread's local_storage before
free main thread. rb_thread_t::local_storage is replaced by fiber's
local storage when forked from fiber, and it should be already freed
when the fiber was destroyed.
* test/ruby/test_fiber.rb (test_fork_from_fiber): add test for fork
from fiber.
