The generator and intrinsic fields in HashTableValue/HashEntry and associated structures and methods are redundant

Reviewed by Geoff Garen.

../JavaScriptCore: 

Move the instrinsic enum out of the DFG, into runtime. Add entires for all host functions
that have an intrinsic in the form of a generated thunk. Remove the thunk pointer from the
hashtable, and make Intrinsic field no longer ifdef on JIT/DFG. In getHostFunction select
a thunk genertaor to use based on the Intrinsic.

Intrinsic is no longer in the DFG namespace, is always in the
hash table. Removed ThunkGenerator.
