k0kubun c86fc2bba5 mjit_compile.c: reduce sp motion on JIT 
This retries r62655, which was reverted at r63863 for r63763.

tool/ruby_vm/views/_mjit_compile_insn.erb: revert the revert.
tool/ruby_vm/views/_mjit_compile_insn_body.erb: ditto.
tool/ruby_vm/views/_mjit_compile_pc_and_sp.erb: ditto.
tool/ruby_vm/views/_mjit_compile_send.erb: ditto.
tool/ruby_vm/views/mjit_compile.inc.erb: ditto.

tool/ruby_vm/views/_insn_entry.erb: revert half of r63763. The commit
  was originally reverted since changing pc motion was bad for tracing,
  but changing sp motion was totally fine. For JIT, I wanna resurrect
  the sp motion change in r62051.
tool/ruby_vm/models/bare_instructions.rb: ditto.
insns.def: ditto.
vm_insnhelper.c: ditto.
vm_insnhelper.h: ditto.

/* Some comments about this file's contents:
- The new format aims to be editable by C editor of your choice;
your mileage might vary of course.
- Each instructions are in following format:
DEFINE_INSN
instruction_name
(type operand, type operand, ..)
(pop_values, ..)
(return values ..)
// attr type name contents..
{
.. // insn body
}
- Unlike the old format which was line-oriented, you can now place
newlines and comments at liberal positions.
- `DEFINE_INSN` is a keyword.
- An instruction name must be a valid C identifier.
- Operands, pop values, return values are series of either variable
declarations, keyword `void`, or keyword `...`. They are much
like C function declarations.
- Attribute pragmas are optional, and can include arbitrary C
expressions. You can write anything there but as of writing,
supported attributes are:
* sp_inc: Used to dynamically calculate sp increase in
`insn_stack_increase`.
* handles_frame: If it is true, VM deals with sp in the insn.
- Attributes can access operands, but not stack (push/pop) variables.
- An instruction's body is a pure C block, copied verbatimly into
the generated C source code.
