Set CFGOnly in MachineUniformityAnalysisPass to false.
If there were new registers created, uniformity analysis needs to be
updated. Previously, with CFGOnly set to true, pass would be skipped
if CFG was preserved.

Thanks, LGTM! I wonder if there's a good way to test this, but I'm not sure. I don't think it's something we usually test.
