Get rid of most uses of ValueRef

Instead pass a const Value & into the functions

With our new inheritance structure, we can get rid of ValueRef
and instead simply pass a pointer to a Value again. Pointers to
Values are safe to use again now, as they are now guaranteed to
be in a place where the GC knows about them.
