variable.c: remove generic ivar support for special constants
Special constants are all frozen since [Feature #8923] and cannot
support ivars. Remove some unused code we had for supporting them.
* variable.c (special_generic_ivar): remove flag
(givar_i, rb_mark_generic_ivar_tbl): remove functions
(rb_free_generic_ivar, rb_ivar_lookup, rb_ivar_delete,
generic_ivar_set, rb_ivar_set, rb_ivar_defined,
rb_copy_generic_ivar, rb_ivar_foreach, rb_ivar_count,
rb_obj_remove_instance_variable):
adjust for lack of ivar support in special constants
* test/ruby/test_variable.rb: test ivars for special consts
* internal.h: remove rb_mark_generic_ivar_tbl decl
* gc.c (gc_mark_roots): remove rb_mark_generic_ivar_tbl call
