Sync DenseMapInfo<FoundDeclTy>::getHashValue() with operator==
Sync DenseMapInfo<FoundDeclTy>::getHashValue() with operator==

The hash function was comparing more fields than operator==, breaking
DenseSets of FoundDeclTy and causing assertion failures.

Incidentally remove the now unused operator< which was only there for
the std::set embedded in the old default implementation of SetVector.
