[LLVMdev] hash extras

[Ryan M. Lefever]

So, after digging around in the old llvm/ADT/hash_map, I think I 
discovered the problem.  Now, if you want to include 
llvm/ADT/HashExtras.h, you have to include the hash_map h file from your 
system (ext/hash_map in my case) and define HASH_NAMESPACE, before you 
include llvm/ADT/HashExtras.  It might be good to include some 
documentation about that for those using HashExtras.

Regards,
Ryan
