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.
