WIP: Add likelyhood to alternatives from stg onwardswip/D4327
Summary:
Adds a Freq value to Stg/Cmm cases/switches/conditionals.
Currently only generates these values by checking alternatives for
bottom expressions.
They are passed along to the backend where they affect conditional generation
slightly.
As it stands runtime improvements seem to be less than expected. This might only be worth merging once we have more branch weights available.
