[PATCH] CodeGenPrepare: Avoid and/or i1 in select conditions.

[Chandler Carruth]

There is no context in the diff, and there appears to be a bunch of unrelated code motion mixed in with the change. Fixing those issues would make it much easier to review.

If the code motion doesn't change any behavior but makes it easier to fit this into the DAG combine, just submit the no-op code motion change first and base this patch off that?
