The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.
Add support for two additional DWARF attributes to encode Objective-C runtime version number. llvm-svn: 64834
