NameError for undefined method.
* load.c (rb_mod_autoload_p), object.c (rb_mod_const_get),
variable.c (rb_f_untrace_var, set_const_visibility), vm_method.c
(rb_mod_{remove,undef,alias}_method, set_method_visibility):
remove inadvertent symbol creation. based on the first patch by
Jeremy Evans at [ruby-core:38447]. [Feature #5089]

* object.c, proc.c, variable.c: more removal of inadvertent symbol
creation. [Feature #5079]

avoid inadvertent symbol creation in reflection methods. based
on a patch by Jeremy Evans at [ruby-core:38367]. [Feature #5072]
* vm_method.c (rb_mod_method_defined)
(rb_mod_{public,private,protected}_method_defined)
(obj_respond_to): ditto.
* parse.y (rb_check_id): new function returns already interned ID
or 0.

* compile.c, eval.c, iseq.c, object.c, parse.y, proc.c, process.c,
thread.c, vm.c, vm_eval.c, vm_insnhelper.c, vm_method.c: don't
declare internal functions.
Note that rb_method_entry_eq() is defined in vm_method.c but
there was a declaration in proc.c with different const-ness.
Now it is declared in method.h with same const-ness to the
definition.
* object.c (rb_mod_module_exec): don't declare functions declared in
include/ruby/intern.h.

Revert of r26135 [ruby-core:27080], as per [ruby-core:32952].

vm_insnhelper.c: use struct rb_constant_entry_t as entry of
RCLASS_CONST_TBL. RCLASS_CONST_TBL has contained VALUE of constant
directly. Now instead rb_const_entry_t is contained in
RCLASS_CONST_TBL, rb_const_entry_t is managed by malloc, and
have not only the value itself but also visibility flag.
This is another preparation for private constant (see
[ruby-dev:39685][ruby-core:32698]).

include/ruby/ruby.h: separate RCLASS_CONST_TBL from RCLASS_IV_TBL.
RCLASS_IV_TBL has contained not only instance variable table but
also constant table. Now the two table are separated to
RCLASS_CONST_TBL and RCLASS_IV_TBL. This is a preparation for
private constant (see [ruby-dev:39685][ruby-core:32698]).

method ids that belong to the class or the singleton class(es) of
the object. [ruby-dev:41613]
* class.c: on the other hand, Module#public_instance_methods, etc.
returns method ids that belong to the module itself (even if the
module is singleton, it does not return method ids of super
class(es); see [ruby-core:28837]).

gain. See [ruby-dev:41067].
* object.c: FL_MARK of some objects by lazy sweep is copied when
RVALUE is cloned. These objects are not marked in the mark phase.
So delete FL_MARK.
* class.c: ditto.

to_ary. Just call. [ruby-core:23738]
* eval.c (rb_check_funcall): new function with method existence
check. returns Qundef when the method does not exist.
* enumerator.c (enumerator_rewind): just call method, using
rb_check_funcall(). [ruby-core:23738]
* error.c (exc_equal): ditto.
* object.c (convert_type): ditto.
* error.c (rb_name_err_mesg_new): export function.
* eval.c (make_exception): ditto.
* io.c (pop_last_hash): return early when the last argument is nil.
* io.c (rb_io_puts): treat T_STRING specially for small
optimization.
* vm_eval.c (raise_method_missing): skip method call if possible
using rb_method_basic_definition_p().
* vm_eval.c (method_missing): ditto.
* test/ruby/test_rubyoptions.rb (TestRubyOptions#test_debug): test
suites changed to ignore exceptions caused by just-call policy.
