OK, I guess the problem is that we don't stream initializer of extern
variables. This leads to Martin's new devirtualization code to no longer be
able to get the optimization done (and same way our folder).  We should check
for error_mark, but also get a testcase for missed optimization and probably
start walking extern initializers when partitioning.
