Daco Harkes d3ea8bff5c [vm/ffi] Fix constant Finalizables
The kernel builder relied on only seeing expressions emitted by the
finalizable transform (variable get and this) as arguments to the fence.

However, other transforms can run later. In this case the expression
was turned into a constant.

This CL changes the implementation to accept any expression rather than
accepting a subset of expressions.
