    [handles] Add a PatchValue method for Handle · ba088da2
    Leszek Swirski authored
    We currently have a pattern of setting a dereferenced Handle location to
    update that Handle's value:
    
      *handle.location() = new_value.ptr()
    
    This is slightly opaque, and definitely not type-safe, so add a new
    Handle<T>::PatchValue method which does this operation.
    
    Ideally we would make Handle::location() return a const pointer to
    discourage this sort of use, but there's a bunch of places where that
    location pointer is used and passed around as a Handle surrogate, so
    those would have to be updated first.
