Subject: [PATCH] Fix #7966: A non-anonymous type can still fail to have a
 symbol. For example, an intersection type.

(We still need the check for the Anonymous flags or else anonymous function tooltips will look like `var lambdaFoo: (Anonymous function)(a: number, b: number) => number'` instead of `var lambdaFoo: (a: number, b: number) => number`)
