Summary: Convergent instrs shouldn't be made control-dependent on other values, but this is basically the whole point of tail duplication. So just bail if we see a convergent instruction.

Don't tail-duplicate blocks that contain convergent instructions.

Summary:
Convergent instrs shouldn't be made control-dependent on other values,
but this is basically the whole point of tail duplication.  So just bail
if we see a convergent instruction.
