not suppress warnings by icc.

RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and
usecase of this macro is not acquire raw pointer, but acquire
read-only pointer. So we rename to better name.
RSTRUCT_RAWPTR() is also renamed to RSTRUCT_CONST_PTR()
(I expect that nobody use it).
* array.c, compile.c, cont.c, enumerator.c, gc.c, proc.c, random.c,
string.c, struct.c, thread.c, vm_eval.c, vm_insnhelper.c:
catch up this change.

random.c:410:32: error: implicit conversion loses integer precision:
'size_t' (aka 'unsigned long') to 'int' [-Werror,-Wshorten-64-to-32]
This cast doesn't cause a problem because len is not bigger than
MT_MAX_STATE.

See this ticet about RGENGC.
* gc.c: Add several flags:
* RGENGC_DEBUG: if >0, then prints debug information.
* RGENGC_CHECK_MODE: if >0, add assertions.
* RGENGC_PROFILE: if >0, add profiling features.
check GC.stat and GC::Profiler.
* include/ruby/ruby.h: disable RGENGC by default (USE_RGENGC == 0).
* array.c: add write barriers for T_ARRAY and generate sunny objects.
* include/ruby/ruby.h (RARRAY_PTR_USE): added. Use this macro if
you want to access raw pointers. If you modify the contents which
pointer pointed, then you need to care write barrier.
* bignum.c, marshal.c, random.c: generate T_BIGNUM sunny objects.
* complex.c, include/ruby/ruby.h: add write barriers for T_COMPLEX
and generate sunny objects.
* rational.c (nurat_s_new_internal), include/ruby/ruby.h: add write
barriers for T_RATIONAL and generate sunny objects.
* internal.h: add write barriers for RBasic::klass.
* numeric.c (rb_float_new_in_heap): generate sunny T_FLOAT objects.
* object.c (rb_class_allocate_instance), range.c:
generate sunny T_OBJECT objects.
* string.c: add write barriers for T_STRING and generate sunny objects.
* variable.c: add write barriers for ivars.
* vm_insnhelper.c (vm_setivar): ditto.
* include/ruby/ruby.h, debug.c: use two flags
FL_WB_PROTECTED and FL_OLDGEN.
* node.h (NODE_FL_CREF_PUSHED_BY_EVAL, NODE_FL_CREF_OMOD_SHARED):
move flag bits.

RBASIC_CLASS(obj) macro which returns a class of `obj'.
This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS
without write barrier (planned).
* RCLASS_SET_SUPER(a, b) set super class of a.
* array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c,
file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c,
parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c,
string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c:
Use above macros and functions to access RBasic::klass.
* ext/coverage/coverage.c, ext/readline/readline.c,
ext/socket/ancdata.c, ext/socket/init.c,
* ext/zlib/zlib.c: ditto.

* random.c (rb_random_ulong_limited): limit is inclusive, but generic
rand method should return a number less than it, so increase for the
difference. [ruby-core:52779] [Bug #7935]

value from 0 upto limit as unsigned long, simillary to
rb_genrand_ulong_limited but with arbitrary RNG object.

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.
