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.

* object.c (rb_obj_inspect): Kernel#inspect: do not call #to_s. A class
can now benefit from the nice default #inspect even if it defines #to_s.
Also, there is no more unexpected change in #inspect result.
* NEWS: Add note about the change.
* bignum.c, io.c, numeric.c, object.c, proc.c, vm.c (Init_*):
Adapt internal structures (by aliasing #inspect to #to_s) so they
don't rely on the removed behavior (#inspect calling overridden #to_s).
* test/ruby/test_object.rb (test_inspect): add tests for Kernel#inspect.
* lib/pp.rb (class PP): do not call #to_s anymore, as #inspect
no more does (mame).
* test/test_pp.rb (class PPInspectTest): remove related assertion (mame).
[ruby-core:43238][Feature #6130]
* test/drb/drbtest.rb (DRbCore#teardown, DRbAry#teardown):
adapt DRb tests with the new change (shirosaki).

Revert "Kernel#inspect: improve consistency and do not call #to_s."
Revert "update PP with recent Kernel#inspect change. Patch by Yusuke Endoh."
r36699 cause test-all failure on test/drb/test_drb.rb and

This reverts commit r33285 because of the message of r33284.

r33282 challenged the precision of floating point but:
* Ruby keeps it as platform dependent
* amd64 won't get this issue because compilers for amd64 uses SSE2 to
calculate floating point numbers instead of x87 FPU.
* this change won't fix the issue under -O
* this commit has no test for the changed behavior

* test/ruby/test_fixnum.rb: add tests for the above change.

bitwise arithmetic with a Bignum. #1792
