Make sure that the sanitizers use the same minimum OS X deployment target as llvm/clang/swift.
Make sure that the sanitizers use the same minimum OS X deployment target as llvm/clang/swift.

in certain clangs require a minimum deployment target of at least 10.7.

I have not investigated further since I am trying to make progress on the
branching scheme.
