delete tool/instruction.rb (2nd try)

Previous commit changed insns.def format. Now is the time for its
generators. In doing so I chose to modernize the system, not just
patch.  My attempt includes

- extensive use of Onigumo regular expressions
- split from one big file (instruction.rb) into separated MVC
- partial view

Also, let me take this opportunity to kill old unused features
such as

- stack caching
- minsns / yasmdata which are never seriously used
- yarvarch document generation (moved to doc/)
- vast majority of unused arguments to insns2vm.rb

This commit generates VM source codes that cleanly compile, and
the generated binary passes tests.  At least for me.

this.on "-I", "--srcdir=DIR", <<~'end'
Historically this option has been passed to the script. This is
supposedly because at the beginning the script was placed
outside of the ruby source tree. Decades passed since the merge
of YARV, now I can safely assume this feature is obsolescent.
Just ignore the passed value here.
end
this.on "-L", "--vpath=SPEC", <<~'end'
Likewise, this option is no longer supported.
end
this.on "--path-separator=SEP", /\A(?:\W\z|\.(\W).+)/, <<~'end'
Old script says this option is a "separator for vpath". I am
confident we no longer need this option.
end
this.on "-Dname", "--enable=name[,name...]", Array, <<~'end'
This option used to override VM option that is defined in
vm_opts.h. Now it is officially unsupported because vm_opts.h to
remain mismatched with this option must break things. Just edit
vm_opts.h directly.
end
this.on "-Uname", "--disable=name[,name...]", Array, <<~'end'
This option used to override VM option that is defined in
vm_opts.h. Now it is officially unsupported because vm_opts.h to
remain mismatched with this option must break things. Just edit
vm_opts.h directly.
end
this.on "-i", "--insnsdef=FILE", "--instructions-def", <<~'end'
This option used to specify alternative path to insns.def. For
the same reason to ignore -I, we no longer support this.
end
this.on "-o", "--opt-operanddef=FILE", "--opt-operand-def", <<~'end'
This option used to specify alternative path to opt_operand.def.
For the same reason to ignore -I, we no longer support this.
end
this.on "-u", "--opt-insnunifdef=FILE", "--opt-insn-unif-def", <<~'end'
This option used to specify alternative path to
opt_insn_unif.def. For the same reason to ignore -I, we no
longer support this.
end
this.on "-C", "--[no-]use-const", <<~'end'
We use const whenever possible now so this option is ignored.
The author believes that C compilers can constant-fold.
end
this.on "-d", "--destdir", "--output-directory=DIR", <<~'begin' do |dir|
THIS IS THE ONLY OPTION THAT WORKS today. Change destination
directory from the current working directory to the given path.
begin
Dir.chdir dir
end
this.on "-V", "--[no-]verbose", <<~'end'
Please let us ignore this and be modest.

* the reason why this file is under unclear situation. All that I know is
* that above provision guarantees this file to exist.
*
* Please let me hesitate to declare something about this nuanced contract. I
* am not in the position to take over other authors' license to merge into my
* one. Changing them to (say) GPLv3 is not doable by myself. Perhaps someday
