Yukihiro "Matz" Matsumoto 5475ea573a vm: add OP_ADDILV/OP_SUBILV for local variable increment

fuse MOVE+ADDI+MOVE and MOVE+SUBI+MOVE patterns into single instructions.
ADDILV/SUBILV add/subtract an immediate to a local variable in-place.
BBB format: a=local, b=working space for method call, c=immediate.

saves 5 bytes per instance (9->4 bytes), 40 occurrences in stdlib.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

Parser: Translates Ruby source code into an abstract syntax tree (AST).
Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
