Now that sp_inc attributes are officially provided as inline
functions. Why not use them directly from the vm core, not just
by the compiler. By doing so, it is now possible for us to
optimize stack manipulations. We can now know exactly how many
words of stack space an instruction consumes before it actually
does. This changeset deletes some lines from insns.def because
they are no longer needed. As a result it reduces the size of
vm_exec_core function from 32,400 bytes to 32,352 bytes on my
machine.
It seems it does not affect performance:

Instead of using magic numbers, let us define a series of attributes
and use them from the VM core. Proper function declarations makes
these attributes inlined in most modern compilers. On my machine
exact same binary is generated with or without this changeset.

as it's helpful for debugging.
I'm not sure what's the good output for RubyVM::TraceInstructions, so I
left it as it is.

which is only used by #router.
To make it private, we need to stop defining them on top-level.

via current directory. It's kind of a global state and fragile to
implementation changes in other places, and how the `Dir.getwd` is set
is not obvious from just reading around `RubyVM::Dumper#initialize` if
it depends on the global state.
tool/ruby_vm/controllers/application_controller.rb: explicitly pass
destdir to RubyVM::Dumper.
tool/ruby_vm/scripts/insns2vm.rb: explicitly pass destdir parsed from
optparse.

`signed` is required for Rasbian (x86_64).
* tool/ruby_vm/views/_insn_stack_increase.erb: specify `signed` explicitly
for systems which use `unsigned` for `char` type.

This was not requested :) but actually easier than the previous
so I just did it anyway.

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.
