Redesign of the scheme for getting the datacon symbol name of a closure in the RTS
Currently, from the closure we get its info table address, and since those are static for Constr closures, we use a hashtable (defined in Linker.c) to relate symbol names obtained when linking and the addresses.
The proposal is to extend the info table with a field for the symbol name, making this process much more straightforward. The trade-off is that this will augment the size of binaries a bit, so we could make this 'labelling' of info tables optional via a flag.
