Improvements

• Extract WasmParser into separate module
  • The new Parser is visitor-based to be friendly to stream translator
• Add InstructionTranslator, which translate parsed instructions into internal VM instruction sequence
  • Translate while collecting popCount/copyCount on value stack
  • This idea is inspired by sidetable design of Ben L. Titzer's work¹
• Remove control label information from execution state

TODO

• Remove legacy parser from WasmKit module
• Direct threaded dispatch e.g. https://gist.github.com/kateinoigakukun/8d71216ded87307da8f558aa1114dcde
