Avoid a crash with `@typedef` in a script file. (#33847) * Avoid a crash with `@typedef` in a script file. Scripts (as opposed to modules) do not have a symbol object. If a script contains a `@typdef` defined on a namespace called `exports`, TypeScript crashes because it attempts to create an exported symbol on the (non-existent) symbol of the SourceFile. This change avoids the crash by explicitly checking if the source file has a symbol object, i.e. whether it is a module. * Add usage of exports.SomeName typedef. * Fix bug at bind site rather than in declare func 2019-10-24 23:04:42 +02:00			`// @allowJS: true`
