Description David Kilzer (:ddkilzer) 2020-07-21 15:53:11 PDT 
WebKit::ObjCObjectGraph::decode() and encode() should use enum ObjCType type.

We can also get rid of default: case labels while we're here to make -Wimplicit-fallthrough emit a warning when a new enum is added.

Removing these.

Keeping these since there are two lines of code.

Thanks!
