Thanks for looking at this, Vladimir.

Relaxing the assert causes the compilation to fail with malformed
control flow (not retryable). My change would cause the compilation to
fail with infinite loop (not retryable). So the end result is the same,
indeed.

Without my change, the IR graph will have IfNodes with a single
projection (for instance). So an "illegal" graph. Wouldn't we want to
keep the graph legal?

Roland.
