This whole discussion started on a version of the patch where we tried to do this in debug-info. It wasn't clear which parts of debug-info emission should be responsible for this. And we don't want to fix-up legitimately corrupted booleans. We'd want this those cases to show up in the debugger. Instruction selection being the one to adjust it for debug ops seemed like the more appropriate place to do this at.
