History
Justin Lebar 9fd0bc5568 [LoopRotate] Don't perform loop rotation if the loop header calls a convergent function. 
Summary:
Calls to convergent functions can be duplicated, but only if the
duplicates are not control-flow dependent on any additional values.
Loop rotation doesn't meet the bar.
