Deserialization is very performance sensitive, so adding this additional check
here isn't a good idea. The right thing to do here is to visit the code space
once deserialization is done, calling the JitCodeEventHandler for just code
objects. Siggi's patch will either do this, or he'll follow-up with his patch
with one that does.
