[PATCH] D11389: [asan] Fix the freopen interceptor to allow NULL instead of a filename

[Kuba Brecka]

Hm, the Linux buildbot didn't like this change: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/19256/steps/check-asan%20in%20gcc%20build/logs/stdio

Interestingly, only the i386 variant failed.  Could it be that that system's libc really doesn't support NULL for `freopen`?  Alexander, could you help me out here?  I reverted the patch until we figure this out.

Thanks!
