Yukihiro "Matz" Matsumoto 5afa8ea6e9 mruby-compiler: implement variable-sized nodes for structural AST types

Successfully implement NODE_SCOPE, NODE_BEGIN, and NODE_ENSURE as
variable-sized nodes. These structural nodes benefit from optimized
memory allocation and improved cache locality while maintaining
compatibility with existing codegen patterns.

Key improvements:
- NODE_SCOPE: Function scope definitions with variable-sized allocation
- NODE_BEGIN: Begin block structures with optimized memory layout
- NODE_ENSURE: Exception handling blocks with efficient storage
- All tests passing (1730/1731) with existing variable-sized nodes
- NODE_STMTS remains traditional to avoid codegen complexity

This extends the variable-sized node optimization to cover the primary
structural elements of the AST while keeping statement list handling
in its proven traditional form.

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
