Iain Sandoe discovered that on intel darwin9, the asan testsuite suffers hundreds of 
failures due to the absence of dispatch calls (Grand Central Dispatch) prior to darwin10.
The attached patch disables building libsanitizer on darwin8 and darwin9 until upstream
decides to support the earlier darwin releases. Bootstrap and regression tested on
x86_64-apple-darwin12. Okay for gcc trunk?
