The size of label references is impossible to determine right now. The first pass of the encoder should collect data to estimate or determine the minimum size of a label reference.

I suspect most instructions can be sized exactly, except for the ones that use labels. For instructions that use labels we can still determine a maximum size. This gives us the ability to determine distance between instructions and allows us to pick a pretty accurate size for labels.

Alternatively, we could decide on some conservative average instruction size and just use the number of instructions as an estimation for label distance.
