Currently, when doing a ASanified build of LLVM (with Clang, compiler-rt and libcxx) via `-DLLVM_USE_SANITIZER=Address` and not using any other options, we already disable building of sanitizer runtimes (because they themselves can’t be sanitized) and also exclude the sanitizer tests.  However, the same is not done for the profiling runtime, which will build fine, but then all the tests fail due to linking errors.  Let’s disable the profiling runtime as well (when LLVM_USE_SANITIZER is set).

This is currently failing on the Darwin ASan+UBSan bot: http://lab.llvm.org:8080/green/job/clang-stage2-cmake-RgSan_check/2425/console
