Avi Kivity 16006949d0 logalloc: make migrator an object, not a function pointer ...

The migrator tells lsa how to move an object when it is compacted.
Currently it is a function pointer, which means we must know how to move
the object at compile time.  Making it an object allows us to build the
migration function at runtime, making it suitable for runtime-defined types
(such as tuples and user-defined types).

In the future, we may also store the size there for fixed-size types,
reducing lsa overhead.

C++ variable templates would have made this patch smaller, but unfortunately
they are only supported on gcc 5+.
