[PATCH] Move sanitizer bots's configs from an external repo to zorg

[Alexey Samsonov]

Oh, regarding your question (3). The log for sanitizer builders is granular enough (see http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/13223), thanks to AnnotatedFactory. We're running a single shell script, but it contains lines like 
  @@@BUILD_STEP check-asan@@@
which form separate cells in build log.
