Justin Lebar	df04d2a1f1	[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.

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.
