While most class field accesses go through accessors, a special
case is if you have a final field (or class) in a non-resilient
module. Then, we were allowed to directly access the field.
However, an earlier hack made it so that this access always went
through a field offset global, which is unnecessary in the case
where the class layout is fully known.
One consequence of this is that 'Array.count' would compile down
to a load from a global followed by an indirect load, instead of
a single load from a constant offset.
