You do realize that with this change, LLVM and Clang must now also be built with RTTI on, right? Otherwise, at least I get linker failures like these:

llvm[3]: Linking Release Shared Library liblldb.dylib
Undefined symbols for architecture x86_64:
  "__ZTIN5clang12SemaConsumerE", referenced from:
      __ZTIN12lldb_private20ASTResultSynthesizerE in liblldbExpression.a(ASTResultSynthesizer.o)

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

(Note: I'm on a Mac, so YMMV.)
