In AddressSanitizer, we have the `MaybeReexec` method to detect when we're running without `DYLD_INSERT_LIBRARIES` (in which case interceptors don't work) and re-execute with the environment variable set.  On OS X 10.11+, this is no longer necessary, but to have ThreadSanitizer supported on older versions of OS X, let's use the same method as well.  This patch moves the implementation from `asan/` into `sanitizer_common/`.
