It will take a while, look a bit on align issue, we have so much code which go
from pointer to large -> small -> large, e.g.
address addr = data() + offset;
return (ImmutableOopMap*) addr;
In this case data() needs to return something with the same alignment as a ptr
and offset must be in even in ptr steps.
