RKSimon added a comment.

I'm going to be on PTO again soon so I'm going to revert this change to unblock you guys, I'll revisit this when I get back - for x86 at least I believe we'll be able to handle it with basic CMOV handling inside X86DAGToDAGISel::matchAddressRecursively.

But for @Whitney's AIX case I'm still not sure.
