We don’t need to regenerate every test.
Similar to how we don’t reformat all of LLVM after a change in clang-format, we can just do that when regenerating tests when they have changes anyway.
So, the churn is that we have extra changes when regenerating a test for a patch.
(In my personal experience there are often extra changes anyway, because metadata was added or similar changes that pass the old CHECKs but show up on a freshly regenerated test.)
