https://bugs.ruby-lang.org/issues/10440#change-49694
* change terminology `arg' to `param'.
* move rb_iseq_t::arg_* to rb_iseq_t::param.
* move rb_iseq_t::arg_size to rb_iseq_t::param::size.
* move rb_iseq_t::argc to rb_iseq_t::param::lead_num.
* move rb_iseq_t::arg_opts to rb_iseq_t::param::opt_num.
* move rb_iseq_t::arg_rest to rb_iseq_t::param::rest_start.
* move rb_iseq_t::arg_post_num to rb_iseq_t::param::post_num.
* move rb_iseq_t::arg_post_start to rb_iseq_t::param::post_start.
* move rb_iseq_t::arg_block to rb_iseq_t::param::block_start.
* move rb_iseq_t::arg_keyword* to rb_iseq_t::param::keyword.
rb_iseq_t::param::keyword is allocated only when keyword
parameters are available.
* introduce rb_iseq_t::param::flags to represent parameter
availability. For example, rb_iseq_t::param::flags::has_kw
represents that this iseq has keyword parameters and
rb_iseq_t::param::keyword is allocated.
We don't need to compare with -1 to check availability.
* remove rb_iseq_t::arg_simple.
* compile.c: catch up this change.
* iseq.c: ditto.
* proc.c: ditto.
* vm.c, vm_args.c, vm_dump.c, vm_insnhelper.c: ditto.
* iseq.c (iseq_data_to_ary): support keyword argument.

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

hooks (old macro name is COLLECT_USAGE_ANALYSIS).
This feature is only for VM developers. (I'm not sure I can use
`VM developers' (the plural form) in this sentence).
If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following
usage collection features:
(1) insntruction: collect intruction usages.
(2) operand: collect operand usages.
(3) register: collect register usages.
The results are stored in
RubyVM::USAGE_ANALYSIS_INSN for (1, 2),
RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and
RubyVM::USAGE_ANALYSIS_REGS for (3).
You can stop collecting usages with
RubyVM::USAGE_ANALYSIS_INSN_STOP(),
RubyVM::USAGE_ANALYSIS_OPERAND_STOP(),
RubyVM::USAGE_ANALYSIS_REGISTER_STOP()
for (1), (2), (3) respectively.
You can also change the hook functions by setting
C level global variables
`ruby_vm_collect_usage_func_(insn|operand|register)'
for (1), (2), (3) respectively.
See codes for more details.
* tool/instruction.rb: fix macro names.
* iseq.c (insn_operand_intern): make it export (used in vm.c).
fix to skip several processes if not needed (pointer is 0).
* vm_dump.c: move codes for collection features to vm.c.
* vm_exec.h: rename macro and function names.
* vm_insnhelper.h: ditto.

`bp' can be calculate by `sp' (stack pointer) of previous frame.
Now, `bp_check' field is remained for debug. You can eliminate
this field by setting VM_DEBUG_BP_CHECK as 0.
* vm_insnhelper.c (vm_base_ptr): add `vm_base_ptr(cfp).
This function calculates base pointer from cfp.
* vm_insnhelper.c (vm_setup_method): push `recv' value on top of
value stack (before method parameters).
This change is for keeping consistency with normal method dispatch.
* insns.def: fix to use vm_base_ptr().
* vm.c (vm_exec): ditto.
* vm_dump.c: remove `bp' related dumps.
* cont.c (fiber_init): fix to check VM_DEBUG_BP_CHECK.
