[PATCH] add supporting ASAN instrumentation on FreeBSD platform

Mon Jan 27 20:50:32 PST 2014

  The change itself looks good.
  I have no ways to test it, so I'd like to see two things:
   1. a lit-style test in test/Instrumentation/AddressSanitizer for the two FreeBSD triples (32 and 64 bit)
   2. A public build bot. Looks like there is one already. Yay!

  You will also need a separate change in compiler-rt
