  [Feature #10440] (Details are described in this ticket)
  Most of complex part is moved to vm_args.c.
  Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
  * introduce rb_call_info_kw_arg_t to represent keyword arguments.

  * rename rb_iseq_t::arg_keywords to arg_keyword_num.
  * rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
    to represent keyword bitmap parameter index.
    This bitmap parameter shows that which keyword parameters are given
    or not given (0 for given).
    It is refered by `checkkeyword' instruction described bellow.
  * rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
    to represent keyword rest parameter index.
  * add rb_iseq_t::arg_keyword_default_values to represent default
    keyword values.
  * rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
    to represent
      (ci->flag & (SPLAT|BLOCKARG)) &&
      ci->blockiseq == NULL &&
      ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.

  * merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
  not. If Hash object and all keys are Symbol literals, they are
  compiled to keyword arguments.

  This instruction check the availability of corresponding keyword.
  For example, a method "def foo k1: 'v1'; end" is cimpiled to the
  following instructions.
    0000 checkkeyword     2, 0  # check k1 is given.
    0003 branchif         9     # if given, jump to address #9
    0005 putstring        "v1"

    0011 putnil
    0012 trace            16
    0014 leave
* insns.def (opt_send_simple): removed and add new instruction
  "opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
  (locate a block variable at last)
* parse.y (vtable_pop): added.
  This function remove latest `n' variables from vtable.
* iseq.c: catch up iseq data changes.
* proc.c: ditto.
* class.c (keyword_error): export as rb_keyword_error().
* common.mk: depend vm_args.c for vm.o.
* hash.c (rb_hash_has_key): export.

nobu 7190c04417 compile.c: store IDs as Symbols
* compile.c (iseq_set_arguments): store local variable IDs in
  temporary list as Symbols.  previously these are stored as
  Fixnums to prevent from GC, but IDs of dynamic symbols can
  exceed Fixnum range and cause RangeError at inverting from
  Fixnum.  [ruby-dev:48564] [Bug #10266]

normal b3a4367ce4 rb_call_info_t: shrink to 96 bytes from 104 bytes on 64-bit
This keeps ci->flag and ci->aux.index consistent across 32-bit
and 64-bit platforms.

ci->flag: VM_CALL_* flags only use 9 bits, currently
ci->aux.index: 2 billion ivars per class should be enough for anybody

This saves around 50K allocations on "valgrind ruby -e exit" on x86-64
before:
  total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
after:
  total heap usage: 48,069 allocs, 19,214 frees, 8,047,266 bytes allocated

* vm_core.h (rb_call_info_t): ci->flag becomes 32-bit unsigned int
  ci->index becomes a 32-bit signed int (from signed long).
  Reorder for better packing on 64-bit, giving an 8 byte reduction
  from 104 to 96 bytes for each ci.

* compile.c (new_callinfo, setup_args, iseq_compile_each,
  iseq_build_from_ary_body): adjust for type changes

* vm_insnhelper.c (vm_getivar): ditto

normal ea4c97904e compile: translate iseq in-place
running "ruby -rpp -e 'pp GC.stat'", a reduction in
malloc usage is shown:

before:
	:malloc_increase=>118784,
	:oldmalloc_increase=>1178736,

after:
	:malloc_increase=>99832,
	:oldmalloc_increase=>1031976,

For "ruby -e exit", valgrind reports over 300K reduction in
overall allocations (and unnecessary memory copies).

before:
  total heap usage: 49,622 allocs, 20,492 frees, 8,697,493 bytes allocated
after:
  total heap usage: 48,935 allocs, 19,805 frees, 8,373,773 bytes allocated

(numbers from x86-64)

v2 changes based on ko1 recommendations [ruby-core:64883]:
- squashed in-place direct thread translation to avoid alloc+copy
- renamed rb_iseq_untranslate_threaded_code to rb_iseq_original_iseq,
  cache new iseq->iseq_original field.

* compile.c (rb_iseq_translate_threaded_code): modify in-place w/o copy
  (rb_vm_addr2insn): new function for debug
  (rb_iseq_original_iseq): ditto
  (iseq_set_sequence): assign iseq_encoded directly
  [Feature #10185]

* vm_core (rb_iseq_t): move original ->iseq to bottom

* iseq.c (iseq_free, iseq_free): adjust for new layout
  (rb_iseq_disasm): use original iseq for dump
  (iseq_data_to_ary): ditto
  (rb_iseq_line_trace_each): ditto
  (rb_iseq_build_for_ruby2cext): use iseq_encoded directly

* vm_dump.c (rb_vmdebug_debug_print_pre): use original iseq
