    Add asserts to other substitution functions · bb956eb8
    niteria authored
    This adds asserts to `substTys`, `substCo` and `substCos` in
    the same spirit as already existing asserts on `substTy`, protecting
    every possible entry point to `subst_ty` and `subst_co`.
    
    I've replaced the violators with unchecked versions.
    
    Test Plan: ./validate --slow
