Yukihiro "Matz" Matsumoto 2fa99a73c2 vm: add OP_MATCHERR instruction for pattern matching errors

Replace 4-instruction sequence (GETCONST + STRING + SEND + RAISEIF)
with single OP_MATCHERR instruction that raises NoMatchingPatternError
with "pattern not matched" message.

Bump RITE binary format version from 0300 to 0400 due to opcode
number shift.

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
