Union types need brackets

[fingerartur]

Even simple union types require brackets (e.g. (number|undefined)) without brackets there is a warning.

/**
* @type {{
*  age: number|undefined, // WARNING - [JSC_TYPE_PARSE_ERROR] Bad type annotation.
* }}
*/
const person = {}

It would be nice to have support for the good old simple bracketless syntaxnumber|undefined.
