CI's name, and then used the StringRef pointing at its old name. I'm
fixing it by storing the name in a std::string, and hoisting the

Split loop exiting edges more aggressively.
...
PHIElimination splits critical edges when it predicts it can resolve
interference and eliminate copies. It doesn't split the edge if the
interference wouldn't be resolved anyway because the phi-use register is
live in the critical edge anyway.
Teach PHIElimination to split loop exiting edges with interference, even
if it wouldn't resolve the interference. This removes the necessary
copies from the loop, which is still an improvement from injecting the
copies into the loop.
The test case demonstrates the improvement. Before:
