- Yay for '-'s and simplifications! - I kept StringMap::GetOrCreateValue for compatibility purposes, this can eventually go away. Likewise the StringMapEntry Create functions still follow the old style. - NIFC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76888 91177308-0d34-0410-b5e6-96231b3b80d8
