allowJs + jsdoc @param + string = compiler Error "Unknown entity name kind"

[wkrueger]

When using the allowJs option and requiring a js file, if in this js file there is a
JSDoc type annotation with a string (e.g. @param input {'opt1'|'opt2'}, the compiler fails with
Unknown entity name kind.

Error: Debug Failure. False expression: Unknown entity name kind.

or:

main.ts

import addPoint = require('./jsinclude')

jsinclude.js

/**
 * @param inp {'type1'}
 */
module.exports.someFunction = (inp) => {
    return inp + '.'
}

Expected
I'm not sure if strings in JSDocs are really valid. If they are, they should be recognized.
On the other hand, I guess that even if a given JSDoc comment is invalid, that should not block the compilation, but fallback to ignoring that JSDoc.

String literal types look pretty easy to add, so I'll just do it.
