This case is the inverse of the one introduced in #155644. The complexity with the inversion is that we need to also invert the condition before shifting it. I had originally planned to only do so when the condition was "cheaply" invertible (i.e. didn't require the xori), but when looking more closely at the diffs I noticed that while the XORI prevents this from being an icount improvement, and actually lengthens slightly the critical path, it does still reduce the number of registers needed.
