[foreign] RFR: 8225552: typedef can interfere with primitive classes

[Henry Jen]

Hi,

Please review another trivial patch[1] that use fully qualified class to avoid wrong type reference.

In this patch, I also entertain a small change to allow —exclude-symbols to filter out typedef, which are generated as type annotation. There is not good reason why we cannot filter out those if so is user wanted.
