af59e9adbd4c972d480d58260b03768c85eb2067 is the first bad commit
commit af59e9adbd4c972d480d58260b03768c85eb2067
Author: Nadav Rotem <<a href="mailto:nrotem@apple.com">nrotem@apple.com</a>>
Date: Fri Dec 7 21:43:11 2012 +0000
When we use the BLEND instruction that uses the MSB as a mask, we can
remove
the VSRI instruction before it since it does not affect the MSB.
Thanks Craig Topper for suggesting this.
