Compiler generated aliases

Check which of the generated alias functions are necessary.

May you elaborate?

The compiler currently generates alias functions for the closure function (model function). We should check after merging #513 which of those alias functions are actually required.

Is this still an issue? It seems that the current closure definitions handle the cases of:

1. No input - for convenient sampling from prior.
2. vi input with no sampler which is convenient for MAP optimization as in Maximum a posterior for Turing models #605.
3. sampler and vi inputs which is used inside of Turing a lot.

Perhaps the only case I am not sure where it is used is when only sampler is input.

The aliases were removed from the compiler in #965. Different methods were defined for (model::Model)(...) instead but all seem to be useful.
