// A custom parser + validator + wasm converter for asm.js:
// http://asmjs.org/spec/latest/
// This parser intentionally avoids the portion of JavaScript parsing
// that are not required to determine if code is valid asm.js code.
// * It is mostly one pass.
// * It bails out on unexpected input.
// * It assumes strict ordering insofar as permitted by asm.js validation rules.
// * It relies on a custom scanner that provides de-duped identifiers in two
//   scopes (local + module wide).
