Merge #756

756: Add const to enforce ownership over pointers r=philberty a=philberty

This consify's a bunch of interfaces in the code base which helps make the ownership
over pointers more clear. These are building blocks from a wider cleanup of the type-checking
code to make it more readable.

- BaseType::get_root
- SubstitutionArgumentMappings::solve_mappings_from_receiver_for_self
- Autoderef adjustments
- GetUsedSubstArgs
- SubstitutionArg field SubstitutionParamMapping
- Backend resolve compile interface
