* Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek2008-02-112-11/+6
| | | | | | | | | | | Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary objects to a profile via dispatch to FoldingSetTrait<T>::Profile(). Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their functionality is now replaced using the above mentioned member template. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46957 91177308-0d34-0410-b5e6-96231b3b80d8
