Thomas Van Lenten d529720e2f If enum aliases overlap in ObjC names skip generating the extras.
Some protos have enum values of "FOO" and "Foo", which the ObjC generation
then makes into the same thing. Just skip generating the enum element for
the duplicate as it would be a compile error because of the name collision.

The descriptors are still generated to support reflection and TextFormat
more completely.
