Hi @tpopp , thanks for reverting. Do you happen to know how to run the Sanitizers tests on X86-64 target? I don't have an X86 testing environment.

I addressed one issue related to `stack-use-after-scope`, but I can not find out the reason for failure `use-of-uninitialized-value`. Maybe the `use-of-uninitialized-value` failure is also the same issue as there is one variable be assigned with returning value of function `shouldReduceRegisterPressure`(This is where failure `stack-use-after-scope` happens.). But I am not sure.

If you can rerun the checks, could you please help to have a verify with the updated patch? Thanks.
