When in js-mode, some latest Javascript keywords are not
highlighted. After looking at js.el, js--keyword-re seems to be missing
the following:

"as", "await, "async", and "of".

"await" is treated as a "future reserved word" in ES6 and promoted to a
keyword in the latest ES8 spec draft.

"async" is treated as a keyword in the AsyncFunctionExpression rule in
ES8 draft.

"of" is treated as a keyword in the for-of iteration production rule in
ES6.

"as" is treated as a keyword in import * as statements in ES6.

References:
ES6: https://www.ecma-international.org/ecma-262/6.0/
ES8: https://tc39.github.io/ecma262/
