These attributes aren't used by other debuggers (& may be confused with other DWARF extensions) so they just waste space (about 1.5% on .dwo file size on a random large program I tested). We could remove the ObjC property ones too, but I figured they were probably more necessary when trying to understand ObjC (I could be wrong though) & so any debugger interested in working with ObjC would use them, perhaps? (also, there are some legacy tests in Clang that test for them - making it one of those annoying cross-project commits and/or cleanup to refactor those tests) llvm-svn: 270613
