Per the vote on WebAssembly#69, this PR removes subtyping from the proposal. List of changes: * Syntax: - remove `nullref` type - rename `anyref` type to `externref` - extend `ref.null` and `ref.is_null` instructions with new immediate of the form `func` or `extern` (this will later have to generalise to a `constype` per the [typed references proposal](https://github.com/WebAssembly/function-references)) * Typing rules: - `ref.null`, `ref.is_null`: determine reference type based on new immediate - `select`, `call_indirect`, `table.copy`, `table.init`: drop subtyping - `br_table`: revert to rule requiring same label types - `elem` segment: drop subtyping - `global` import: drop subtyping (link time) * Remove subtyping rules and bottom type. * Revert typing algorithm (interpreter and spec appendix). * JS API: - remove `"nullref"` - rename `"anyref"` to `"externref"` * Scripts: - rename `ref` result to `ref.extern` - rename `ref.host` value to `ref.extern` - drop subtyping from invocation type check * JS translation: - extend harness with separate eq functions for each ref type * Adjust tests: - apply syntax changes - remove tests for subtyping - change tests exercising subtyping in other ways

Hi, it seems there's a little typo here.
