Doesn't `CompiledIC::set_to_clean()` handle virtual call sites? If you referred to `CompiledDirectCall::set_to_clean()` instead, I believe no miscommunication happened here. What I meant is that `CompiledDirectCall::set_to_clean()` must not *zero out the [method, entry} fields in the stub* by calling `CompiledDirectCall::set_stub_to_clean()`. The latter is currently unused. Should it be removed entirely perhaps?
