Yukihiro "Matz" Matsumoto 2495cd3c52 mruby-compiler: simplify node allocation in parse.y with helper

introduce new_node() helper and NEW_NODE() macro to eliminate repetitive
allocation and header initialization pattern across 64 new_* functions.

before: each function required 2-3 lines for allocation:
  struct mrb_ast_xxx_node *n = (...)parser_palloc(p, sizeof(...));
  init_var_header(&n->header, p, NODE_XXX);

after: single line with type-safe macro:
  struct mrb_ast_xxx_node *n = NEW_NODE(xxx, NODE_XXX);

saves approximately 128 lines while maintaining readability and providing
central point for future allocation logic changes.

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
