I think we're going to want to look at the gimple IR and search for the 
MIN/MAX expressions rather than the instructions.  Given we don't know 
where the transformation is going to land (yet), you can probably start 
with -fdump-tree-optimized and scanning the .optimized dump.

We can still do that and have the test be target specific.
