[analyzer] Temporary remove c++analyzer to recreate it as a separate file, not a symlink.

[analyzer] Recreated as a file.

[analyzer] RetainCountChecker: don't track through xpc_connection_set_context.

It is unfortunate that we have to mark these exceptions in multiple places.
This was already in CallEvent. I suppose it does let us be more precise
about saying /which/ arguments have their retain counts invalidated -- the
connection's is still valid even though the context object's isn't -- but
we're not tracking the retain count of XPC objects anyway.
