Yukihiro "Matz" Matsumoto f98d6414dc codegen.c: chunk array literals at 64 elements to reduce register pressure

Array literals were being built by loading all elements into registers
before constructing the array, requiring nregs proportional to the array
size (e.g. nregs=99 for 100 elements). This exceeds mruby/c's register
limit. Restore 3.4-era chunking at GEN_LIT_ARY_MAX (64) elements.

fixes mruby/mruby#6731

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
