* [Feature #12005] Unify Fixnum and Bignum into Integer

* include/ruby/ruby.h (rb_class_of): Return rb_cInteger for fixnums.

* insns.def (INTEGER_REDEFINED_OP_FLAG): Unified from
  FIXNUM_REDEFINED_OP_FLAG and BIGNUM_REDEFINED_OP_FLAG.

* vm_core.h: Ditto.

* vm_insnhelper.c (opt_eq_func): Use INTEGER_REDEFINED_OP_FLAG instead
  of FIXNUM_REDEFINED_OP_FLAG.

* vm.c (vm_redefinition_check_flag): Use rb_cInteger instead of
  rb_cFixnum and rb_cBignum.
  (C): Use Integer instead of Fixnum and Bignum.

* numeric.c (fix_succ): Removed.
  (Init_Numeric): Define Fixnum as Integer.

* bignum.c (bignew): Use rb_cInteger instead of Rb_cBignum.
  (rb_int_coerce): replaced from rb_big_coerce and return fixnums
  as-is.
  (Init_Bignum): Define Bignum as Integer.
  Don't define ===.

* error.c (builtin_class_name): Return "Integer" for fixnums.

* sprintf.c (ruby__sfvextra): Use rb_cInteger instead of rb_cFixnum.

* ext/-test-/testutil: New directory to test.
  Currently it provides utilities for fixnum and bignum.

* ext/json/generator/generator.c: Define mInteger_to_json.

* lib/mathn.rb (Fixnum#/): Redefinition removed.
