vabr 94bf354af5 Raise SyntaxError on let [ starting an ExpressionStatement

ES2017 forbids the sequence of tokens "let [" in in expression statements [1].

This CL makes ParserBase report those instances as SyntaxError. It also adds a
customised error message for that, because the standard "Unexpected token" is
not applicable: "let" itself is not forbidden in those context, only the
sequence of "let [".
