[llvm] MachineUniformityAnalysis: Pass is incorrectly initialized as CFGOnly (PR #125511)

[Petar Avramovic via llvm-commits]

https://github.com/petar-avramovic created https://github.com/llvm/llvm-project/pull/125511

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.

 CFGOnly

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
