* vm_dump.c (backtrace): use rip in the saved context for the case
the SIGSEGV is received when the process is in userland.
Note that ip in the stack should be used if the signal is received
when it is in kernel (when it is calling syscall) [Bug #12711]

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:🎏: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.

beyond signal trampoline, and as described in r38342 it can't
trace on -O because it see stack frame pointers.
libunwind unw_backtrace see dwarf information in the binary

DragonFly which cannot be found by AC_REPLACE_FUNCS(). This
workaround enforces the fact that they exist on DragonFly.

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.
