    Retrieving the datacon of an arbitrary closure · ab5b8aa3
    mnislaih authored 
    This patch extends the RTS linker and the dynamic linker so that it is possible to find out the datacon of a closure in heap at runtime:
- The RTS linker now carries a hashtable 'Address->Symbol' for data constructors
- The Persistent Linker State in the dynamic linker is extended in a similar way.

Finally, these two sources of information are consulted by:

> Linker.recoverDataCon :: a -> TcM Name
